Hello,

I'm using PHP FPM on Debian Squeeze with PHP 5.3.27. I have the following
pool configuration:

[bmde_prod]
listen = /var/lib/php5-sockets/bmde_prod.socket

pm = dynamic
pm.max_children = 250
pm.start_servers = 15
pm.min_spare_servers = 14
pm.max_spare_servers = 15
pm.max_requests = 1000

listen.backlog = -1

In normal operation, I have 16-20 pool processes running. From time to
time, the pool rises from 16-20 pool processes to maximum of 250 processes.
But there is no traffic from outside, after the limit of 250 is reached the
whole pool gets unavailable.


When I start a strace -n 3000 -f to all (250) running pool processes, I get
the following output:


[pid 20173] <... poll resumed> ) = 0 (Timeout)
[pid 20173] poll([{fd=9, events=POLLIN|POLLPRI}], 1, 0) = 0 (Timeout)

.... and a lot more of the same lines.


If I kill one or two processes of the pool, the pool itself gets available
again and lowers the pool processes to normal operation.

Does anybody know that's about that?

Thanks,
Jonas

Hi,

we've seen the following happen a few times, and I'd like to know who is
sending the SIGKILL, and if I can do anything about that.

We run a lengthy update process in a shutdown function after the response
has been flushed with fastcgi_finish_request(). It usually takes 6-10s, but
under high load, it can take 40s or more. Sometimes, after roughly 30s (sometimes
more, sometimes less), the process performing the update receives a SIGKILL.
While we can usually recover from this (by simply restarting the update), the
SIGKILL may just hit us while we own the shared memory lock to update APC. This
lock is _not_ freed when the process dies, so that all further attempts to
access APC block.

In the PHP error_log, the typical order of events is:

[26-Feb-2014 15:02:01] update start (PID 27582)
[26-Feb-2014 15:02:01] WARNING: [pool php] seems busy (you may need to increase pm.start_servers, or pm.min/max_spare_servers), spawning 8 children, there are 0 idle, and 48 total children
[26-Feb-2014 15:02:02] WARNING: [pool php] seems busy (you may need to increase pm.start_servers, or pm.min/max_spare_servers), spawning 16 children, there are 0 idle, and 53 total children
[...] more of the same

[26-Feb-2014 15:02:08] WARNING: [pool php] server reached pm.max_children setting (80), consider raising it
[26-Feb-2014 15:02:29] WARNING: [pool php] child 27582 exited on signal 9 (SIGKILL) after 103.188030 seconds from start


So, my question is, who is sending a SIGKILL to the process, why is
it done, and can I influence this behaviour in any way?

As far as I can tell, the SIGKILL is not caused by exceeding the
PHP max_execution_time (the overall CPU time used is smaller than
the configured limit) or the cpu time ulimit (set to unlimited).


thanks,


rainer

Hi, I recently had an outage with a VM that runs Ubuntu Linux 12.04 64bit
in an ESX Vmware environment. The php is 5.3 We've been having issues
with php-fpm needing to be restarted when the system becomes unusable. The
cacti graph of the memory of during the event is really confusing to me.

See attached. Can someone please tell me what the OS/Kernel/php-fpm was
doing that caused real memory to increase, cache memory to deplete, and
unused memory to increase? During this, we ran out of swap.

If anyone knows what went on, I would really appreciate it.

Please let me know if there is some other information you need. Simply
stopping and starting php-fpm fixed the issue. We suspect a poorly
writting app causing the usage and we are zeroing in on that, but any help
with understanding what happened would be wonderful.

Thanks!!

Pete

Hi,
I have been trying to setup nginx and fpm on our production machine.It already runs apache + mod-php and it serves around 50 Req/s with high memory usage but load average is below 1 on an 8 core 16GB machine.

I installed nginx + php-fpm via socket on this box and tried to put the same amount of traffic which apache bears with LVS but it accepts around 60-70 Req/sec only, if I try to increase it to 100 + the system load shoots and the php-fpm active processes reaches its limit and it stalls .

So is it intended to behave this way ? because what I have read on the forums/ blogs etc is that nginx with php-fpm outperforms apache.
I could be somethings wrong ,need suggestions and help to answer this question.


Thanks
Rajat

I am developing an application on my localhost that uses Nginx/PHP5-fpm from Dotdeb (Linux Neptune 3.3), and have come across a bug in the handling of assignment of session_id() that doesn't occur under Apache/Lightspeed with PHP (on my host server).

This code:
session_id($date . '-' . $userid . '-' . $_SESSION['till']);

has to be modified to be:

$_SESSION['id']=($date . '-' . $userid . '-' . $_SESSION['till']);

and then use the $_SESSION['id'] instead of the true session_id().

The symptom is that the session is destroyed when going to the next page.

Hi all!
I change server, from an HP with 2 CPU Xeon quad core 8gb ram to a Dell with 2 CPU Xeon quad core and 16gb ram, both servers are with FreeBSD and I'm using same php-fpm and nginx configurations.

But I've a trouble about php-fpm, my log have a really huge of:
sonewconn: pcb 0xfffffe01f2c6f870: Listen queue overflow: 193 already in queue awaiting acceptance

I use PHP 5.3.28 with Suhosin-Patch

that's my php-fpm configuration:

[global]
pid = run/php-fpm.pid

error_log = /var/log/php-fpm/error.log
log_level = error

emergency_restart_threshold = 10
emergency_restart_interval = 1m

process_control_timeout = 10s
process.max = 0

[www]
user = www
group = www
security.limit_extensions = .php

listen = /tmp/php-fpm.$pool.sock
listen.allowed_clients = 127.0.0.1
listen.backlog = -1

pm = static
pm.max_children = 8
pm.max_requests = 10000000

request_slowlog_timeout = 40s
slowlog = /var/log/php-fpm/slow.$pool.log

env[TMP] = /tmp
env[TMPDIR] = /tmp
env[TEMP] = /tmp


Any idea?

There is this issue in the server that is not allowing me to run correctly
php-fpm, but despite this issue everything is running with a problem of 524
CloudFlare time out every time I SEND, POST ,etc

My server Configuration is: 12.04.4 LTS, Precise Pangolin + NGINX + ionCube
+ igBinary + CloudFlare (php-fpm)

Every time I try to start PHP-FPM I get stuck until I open a new session .

PHP-FPM LOG says this :

> [02-May-2014 02:51:05] ERROR: An another FPM instance seems to already
> > listen on /var/run/php5-fpm.sock
> >
> [02-May-2014 02:51:05] ERROR: FPM initialization failed


So far what I've investigate, with my short knowledge is that I have CGI
php.ini, PHP-FPM php.ini CLI php.ini

https://www.dropbox.com/s/nddqpmf0937x739/Screenshot%202014-05-02%2011.19.11.png

that maybe are in conflict

also php-fpm is correctly configured (Well that is what I think):
www.conf:

my NGNIX.conf is just the same that H5BP-NGINX Config provied

HI all,
I want to ask how to use statistics feature in FPM in PHP5.2.x. I notice
that fpm in php5.2.x use the xml syntax. but when i add <value
name="status">/status</value> into fpm 's configuration file, it report
Warning, unknown setting 'status' in section '/configuration/workers/pool'


I have found the xml syntax example from here:
http://www.fatbsd.com/fpm/xml.html. and I add status setting like that, but
the fpm doesn't work.

I guess the fpm in php.5.2.x doesn't support statistics feature, right? is
anybody can tell me?

Hello,
I'm quite new to Nginx, but so far i've had reasonable success in getting things to work, until I try and use the Sympa mailing list web interface.

With this config:

server {
listen 80;
server_name www.tld.co.uk;


location /static-sympa {
alias /var/lib/sympa/static_content;
}

location /sympa {
root /usr/lib/cgi-bin/sympa;
gzip off;
fastcgi_pass unix:/etc/php5/fpm/socks/www.tld.co.uk.sock;
fastcgi_split_path_info ^(/sympa)(.+)$;
include /etc/nginx/fastcgi_params;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param REMOTE_USER $remote_user;
fastcgi_param SCRIPT_FILENAME $document_root/wwsympa-wrapper.fcgi;
fastcgi_intercept_errors on;
}

And with this in the /etc/nginx/fastcgi_params file:

fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;

fastcgi_param SCRIPT_FILENAME $request_filename;
fastcgi_param PATH_INFO $fastcgi_script_name;
fastcgi_param SCRIPT_NAME $fastcgi_script_name;
fastcgi_param REQUEST_URI $request_uri;
fastcgi_param DOCUMENT_URI $document_uri;
fastcgi_param DOCUMENT_ROOT $document_root;
fastcgi_param SERVER_PROTOCOL $server_protocol;

fastcgi_param GATEWAY_INTERFACE CGI/1.1;
fastcgi_param SERVER_SOFTWARE nginx/$nginx_version;

fastcgi_param REMOTE_ADDR $remote_addr;
fastcgi_param REMOTE_PORT $remote_port;
fastcgi_param SERVER_ADDR $server_addr;
fastcgi_param SERVER_PORT $server_port;
fastcgi_param SERVER_NAME $server_name;

# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param REDIRECT_STATUS 200;


On trying to access www.tld.co.uk/sympa I get nothing at all in the Nginx error log, and the following in the Nginx access log:
<client IP> - - [18/May/2014:23:00:04 +0100] "GET /sympa HTTP/1.1" 200 6205 "-" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/33.0.1750.152 Safari/537.36"

Even with php5-fpm configured for debug logging, nothing happens in the php5-fpm.log file either (and I can see that things do happen in this file for other Nginx web pages like postfixadmin or roundcube, so am reasonably confident that php5-fpm is correct).

What puzzles me most is that what gets posted to the clients web browser when visiting www.tld.co.uk/sympa is the following:

I hope that somebody on this list can please help me understand what it is doing.

Many Thanks in advance!

Just noticed this small but funny thing when looking at my php-fpm.conf
file tonight:

; The number of child processes created on startup.
> ; Note: Used only when pm is set to 'dynamic'
> ; Default Value: min_spare_servers + (max_spare_servers -
> min_spare_servers) / 2
> ;pm.start_servers = 20
>

It seems to me like this equation:

min_spare_servers + (max_spare_servers - min_spare_servers) / 2
>

can actually be reduced to:

(min_spare_servers + max_spare_servers) / 2
>


Or am I missing something obvious?

Hi,
I need some help with a server running a single website. The memory is increasing really fast, about 1GB per day.
Restarting php-fpm and nginx is not freeing any memory.
I need to reboot the whole server every 15 days, I can't figure out the problem since 4 months now.

Here is the status and conf files, I hope you can help ;)

Hi,

I have a PHP application that outputs chunk-encoded data (http://en.wikipedia.org/wiki/Chunked_transfer_encoding) along with a "transfer-encoding: chunked" header.

This works as expected using apache but not when I'm using nginx+php-fpm.

The "transfer-encoding: chunked" header is replaced by a "transfer-encoding: identity" header and this makes it impossible for the client to properly decode the response since it doesn't know that the data is chunk-encoded.

Anyone know how to solve this? I'm using nginx/1.4.6 (Ubuntu) and PHP 5.5.9-1ubuntu4.

Thanks.

Hello,

I hope you can help me.
I'm running NGINX with PHP-FPM and since some weeks my master process is crashing silently. (nothing about a crash in any logs)
The Nginx and php version are irrelevent because this problem persists over some versions.
But the problem occurred after I upgraded to Ubuntu 14.04.
The strange thing is: Monit tells me that php-fpms master process is crashing once a week exactly on Sunday 6:50 or Monday 6:50 UTC +1. (Mabe something with logrotation?)
The only crazy thing I can see is, that shortly before php is crashing, its testing its configuration file multiple times / second.
I cannot see any high load or anything at the time of the crash.
I even reset every configuration file of php-fpm and installed the defaults, or set the pollig method to poll or epoll.
The latest crash was yesterday 6:50. Short before the crash (5 minutes) and after the crash (1 hour) syslog said:
kernel: [C.D] php5-fpm[8380]: segfault at X ip Y sp Z error 6 in php5-fpm[400000+7ff000]
kernel: [C.E] Core dump to |/usr/share/apport/apport A 11 0 B pipe failed

How can I fix the php and the apport error?

Thank you!

Hi all, How are you?

I am trying to setup a new environment with the following characteristics:
* CentOS version 6.5 (64 bits);
* Nginx version 1.6.1;
* PHP-fpm version 5.3.3-27;
* PHP version 5.3.3;
* Mysql version 5.1.73;

This is my /etc/nginx/conf.d/default.conf file:
------------------start default.conf
server {
listen 80;
server_name localhost;

root /usr/share/nginx/html;

location / {
root /usr/share/nginx/html;
index index.html index.htm;
}

index index.html index.htm index.php default.php;

error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}

location ~ \.php$ {
fastcgi_pass unix:/var/run/php-fpm.socket;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
include fastcgi_params;
}
}

------------------end default.conf

This is small part of /etc/php-fpm.d/www.conf concerned with nginx:
------------------start www.conf
[www]
listen = /var/run/php-fpm.socket
listen.owner = nginx
listen.group = nginx
listen.mode = 0666
user = nginx
group = nginx
pm.status_path = /status
------------------start www.conf

I have created a index.php page at /usr/share/nginx/html folder with the following content:
------------------start index.php
<?php
phpinfo();
?>
------------------start index.php

The issue is that when I try to access http://localhost/info.php thus nginx provides me info.php source code.
I mean, when I try to access http://localhost/info.php then nginx pushes info.php source code without any further processing.
Therefore, It looks like that there is a configuration problem between nginx and PHP-fpm, but I can not figure out what is going on.
It is also important to note that nginx and PHP-fpm errors logs does not registry any kind of error/issue.

Please, May someone help me?I have no idea of what is going on.

I appreciate any help you can give me,
Roger

Hi,

I'm running Ubuntu 14.04 with nginx 1.7.4 (ppa:nginx/development) and PHP 5.6 (ppa:ondrej/php5-5.6).

Everything was working just fine with nginx 1.7.1 but when I upgraded to 1.7.4 every single PHP page is blank, even phpinfo.

I tried rebuilding my VPS and starting over from scratch but no matter what I did I still get a blank page with 1.7.4.

As soon as I revert to nginx 1.7.1 or the latest build available with the default Ubuntu LTS 14.04 repository there's no problem.

Has anyone else experienced this with 1.7.4-1+trusty? What might be the cause?

Here is the config I'm testing with:

server {
listen 80 default_server;
listen [::]:80 default_server ipv6only=on;

root /var/www/domain.com;
index index.php index.html index.htm;

server_name domain.com;

location / {
try_files $uri $uri/ =404;
}

error_page 404 /404.html;
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}

location ~ \.php$ {
try_files $uri =404;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_index index.php;
include fastcgi_params;
}
}

I have a high traffic site (we are talking about millions of pageviews per month here) and i am having trouble optimizing php-fpm as each process is using a huge amount of cpu(15% to 99%).My load average is typically 20 at peak times (which is huge).



http://gyazo.com/866d574730def373e6c79e074fd52fcd

My server specs(i upgraded both ram and cpu in an attempt to solve the problem).My site uses just Nginx+PHP-FPM , there is no database or anything else but i use Zend Opcache

nginx version: nginx/1.7.5

WARNING: [pool www] seems busy (you may need to increase pm.start_servers, or pm.min/max_spare_servers), spawning 32 children, there are 76 idle, and 338 total children

My php-fpm config

pm = dynamic
pm.max_children = 800
pm.start_servers = 120
pm.min_spare_servers = 80
pm.max_spare_servers = 160
pm.max_requests = 500

Just started getting 502 Bad Gateway and in the nginx error log I see:

upstream sent invalid status "" while reading response header from upstream

When I restarted php-fpm, everything went back to normal and working. Did something with php-fpm just go wrong? I don't see anything in the php-fpm error logs. What typically causes this, and what are some fixes to prevent it from happening again.

I am running Joomla + CiviCRM and the php-fpm requierements are much differents between the two.
I am trying to select the proper upstream php based on the args, like that "/index.php?Itemid=1050&option=com_civicrm&view=Events&lang=fr".
I would like all pages refering to com_civicrm to be handled by a specific upstream and all the rest by another. I am pretty sure that the upstream hash should do the job but I can't find how.

Any suggestion?

Hello,

It happens when I try to save any configuration with a wordpress user, like updoading a file or changing anything of the aspect of a web page.

The directory /var/lib/nginx/fastcgi is empty, and these are their owners/permissions:

ls -al /var/lib/nginx/fastcgi
total 8
drwx------ 2 panchito root 4096 feb 28 18:08 ./
drwx------ 7 root root 4096 feb 28 18:08 ../

I changed permissions to it to 706, or even 777 with the same results.

I built my own LEMP "home web server" with this:

I paste too any configuration from my nginx.conf I think can be useful for you:

user panchito grupo_panchito;
worker_processes 1;
server {
listen 80;
server_name localhost;

#charset koi8-r;

#access_log logs/host.access.log main;

location / {

; By default the status page output is formatted as text/plain. Passing either
; 'html', 'xml' or 'json' in the query string will return the corresponding
; output syntax. Example:
; http://www.foo.bar/status
; http://www.foo.bar/status?json
; http://www.foo.bar/status?html
; http://www.foo.bar/status?xml
;
; By default the status page only outputs short status. Passing 'full' in the
; query string will also return status for each pool process.
; Example:
; http://www.foo.bar/status?full
; http://www.foo.bar/status?json&full
; http://www.foo.bar/status?html&full
; http://www.foo.bar/status?xml&full
; The Full status returns for each process:
; pid - the PID of the process;
; state - the state of the process (Idle, Running, ...);
; start time - the date and time the process has started;
; start since - the number of seconds since the process has started;
; requests - the number of requests the process has served;
; request duration - the duration in µs of the requests;
; request method - the request method (GET, POST, ...);
; request URI - the request URI with the query string;
; content length - the content length of the request (only with POST);
; user - the user (PHP_AUTH_USER) (or '-' if not set);
; script - the main script called (or '-' if not set);
; last request cpu - the %cpu the last request consumed
; it's always 0 if the process is not in Idle state
; because CPU calculation is done when the request
; processing has terminated;
; last request memory - the max amount of memory the last request consumed
; it's always 0 if the process is not in Idle state
; because memory calculation is done when the request
; processing has terminated;
; If the process is in Idle state, then informations are related to the
; last request the process has served. Otherwise informations are related to
; the current request being served.

; Default Value: not set
;pm.status_path = /status

; The ping URI to call the monitoring page of FPM. If this value is not set, no
; URI will be recognized as a ping page. This could be used to test from outside
; that FPM is alive and responding, or to
; - create a graph of FPM availability (rrd or such);
; - remove a server from a group if it is not responding (load balancing);
; - trigger alerts for the operating team (24/7).
; Note: The value must start with a leading slash (/). The value can be
; anything, but it may not be a good idea to use the .php extension or it

; it can accept the following format:
; - %{seconds}d (default)
; - %{miliseconds}d
; - %{mili}d
; - %{microseconds}d
; - %{micro}d
; %e: an environment variable (same as $_ENV or $_SERVER)
; it must be associated with embraces to specify the name of the env
; variable. Some exemples:
; - server specifics like: %{REQUEST_METHOD}e or %{SERVER_PROTOCOL}e
; - HTTP headers like: %{HTTP_HOST}e or %{HTTP_USER_AGENT}e
; %f: script filename
; %l: content-length of the request (for POST request only)
; %m: request method
; %M: peak of memory allocated by PHP
; it can accept the following format:
; - %{bytes}M (default)
; - %{kilobytes}M
; - %{kilo}M
; - %{megabytes}M
; - %{mega}M
; %n: pool name
; %o: output header
; it must be associated with embraces to specify the name of the header:
; - %{Content-Type}o
; - %{X-Powered-By}o
; - %{Transfert-Encoding}o
; - ....
; %p: PID of the child that serviced the request
; %P: PID of the parent of the child that serviced the request
; %q: the query string
; %Q: the '?' character if query string exists
; %r: the request URI (without the query string, see %q and %Q)
; %R: remote IP address
; %s: status (response code)
; %t: server time the request was received
; it can accept a strftime(3) format:
; %d/%b/%Y:%H:%M:%S %z (default)
; %T: time the log has been written (the request has finished)
; it can accept a strftime(3) format:
; %d/%b/%Y:%H:%M:%S %z (default)
; %u: remote user
;
; Default: "%R - %u %t \"%m %r\" %s"
;access.format = "%R - %u %t \"%m %r%Q%q\" %s %f %{mili}d %{kilo}M %C%%"

; The log file for slow requests
; Default Value: not set
; Note: slowlog is mandatory if request_slowlog_timeout is set
;slowlog = log/$pool.log.slow

; The timeout for serving a single request after which a PHP backtrace will be
; dumped to the 'slowlog' file. A value of '0s' means 'off'.
; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)
; Default Value: 0
;request_slowlog_timeout = 0

; The timeout for serving a single request after which the worker process will
; be killed. This option should be used when the 'max_execution_time' ini option
; does not stop script execution for some reason. A value of '0' means 'off'.
; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)
; Default Value: 0
;request_terminate_timeout = 0

; Set open file descriptor rlimit.
; Default Value: system defined value
;rlimit_files = 1024

; Set max core size rlimit.
; Possible Values: 'unlimited' or an integer greater or equal to 0
; Default Value: system defined value
;rlimit_core = 0

; Chroot to this directory at the start. This value must be defined as an
; absolute path. When this value is not set, chroot is not used.
; Note: you can prefix with '$prefix' to chroot to the pool prefix or one
; of its subdirectories. If the pool prefix is not set, the global prefix
; will be used instead.
; Note: chrooting is a great security feature and should be used whenever
; possible. However, all PHP paths will be relative to the chroot
; (error_log, sessions.save_path, ...).
; Default Value: not set
;chroot =

; Chdir to this directory at the start.
; Note: relative path can be used.
; Default Value: current directory or / when chroot
;chdir = /var/www

; Redirect worker stdout and stderr into main error log. If not set, stdout and
; stderr will be redirected to /dev/null according to FastCGI specs.
; Note: on highloaded environement, this can cause some delay in the page
; process time (several ms).
; Default Value: no
;catch_workers_output = yes

; Limits the extensions of the main script FPM will allow to parse. This can
; prevent configuration mistakes on the web server side. You should only limit
; FPM to .php extensions to prevent malicious users to use other extensions to
; exectute php code.
; Note: set an empty value to allow all extensions.
; Default Value: .php
;security.limit_extensions = .php .php3 .php4 .php5

; Pass environment variables like LD_LIBRARY_PATH. All $VARIABLEs are taken from
; the current environment.
; Default Value: clean env
;env[HOSTNAME] = $HOSTNAME
;env[PATH] = /usr/local/bin:/usr/bin:/bin
;env[TMP] = /tmp
;env[TMPDIR] = /tmp
;env[TEMP] = /tmp

; Additional php.ini defines, specific to this pool of workers. These settings
; overwrite the values previously defined in the php.ini. The directives are the
; same as the PHP SAPI:
; php_value/php_flag - you can set classic ini defines which can
; be overwritten from PHP call 'ini_set'.
; php_admin_value/php_admin_flag - these directives won't be overwritten by
; PHP call 'ini_set'
; For php_*flag, valid values are on, off, 1, 0, true, false, yes or no.

; Defining 'extension' will load the corresponding shared extension from
; extension_dir. Defining 'disable_functions' or 'disable_classes' will not
; overwrite previously defined php.ini values, but will append the new value
; instead.

; Note: path INI options can be relative and will be expanded with the prefix
; (pool, global or /usr)

; Default Value: nothing is defined by default except the values in php.ini and
; specified at startup with the -d argument
;php_admin_value[sendmail_path] = /usr/sbin/sendmail -t -i -f www@my.domain.com
;php_flag[display_errors] = off
;php_admin_value[error_log] = /var/log/fpm-php.www.log
;php_admin_flag[log_errors] = on
;php_admin_value[memory_limit] = 32M
