Problem with orhpaned fcgi php processes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi.

We have a webserver with apache 2.2.14, PHP 5.3.2.
PHP is executed using mod_fcgid (see bottom). Everything works fine but sometimes, and we still have to figure out what triggers this, when php processes are "rotated" they remain active and orphaned: apache spawns new php processes and the old ones remains on the system.
Killing them doesn't always kicks them away. More likely an "apache2ctl graceful" frees the system from this stale processes.
We found this in error log:
[Tue Jun 18 20:49:54 2013] [warn] mod_fcgid: process 2009 graceful kill fail, sending SIGKILL
from what I found searching around this is quite normal, but that's all I found in apache logs during one of this processes leak.

This event is luckily seldomly happening, usually apache and php operate normally and with no problems during fcgid childrens renewal. 
How can we understand what's going wrong in these situations?
thanks

P.s. posting here some configs:

mod_fcgid config in site:
    <IfModule mod_fcgid.c>
      SuexecUserGroup domain domain
      <Directory /var/www/fomain.it/htdocs/>
        AddHandler fcgid-script .php
        FCGIWrapper /var/www/fcgi/domain.it/fcgi-starter-php .php
        Options +ExecCGI -Indexes
        AllowOverride FileInfo Options
        Order allow,deny
        Allow from all
      </Directory>
      <Directory /var/www/fcgi/domain.it/>
        AllowOverride None
        Options +ExecCGI MultiViews -Indexes
        Order allow,deny
        Allow from all
      </Directory>
    </IfModule>

/var/www/fcgi/domain.it/fcgi-starter-php:
#!/bin/sh

PHPRC=/var/www/fcgi/domain.it/php/

export PHPRC
PHP_FCGI_CHILDREN=8
export PHP_FCGI_CHILDREN
PHP_FCGI_MAX_REQUESTS=5000
export PHP_FCGI_MAX_REQUESTS

exec /usr/lib/cgi-bin/php $1
