I am using the following versions of Apache and mod_fgid:
- Apache 2.2.4, apachelounge version
- mod_fcgid 2.2, the version "2.2a" currently available on the download page
The problem I am having is that, though my FastCGI configuration seems to work properly otherwise, the following mod_fcgid directives never have any effect:
- IdleTimeout
- MaxRequestsPerProcess
- ProcessLifeTime
The FastCGI'd processes (php, in this case) continue to live until they are killed or segfault. Excess processes are never culled by mod_fcgid, nor can I control the IdleTimeout (which is my ultimate goal).
Does anyone have any idea what might be the cause of this? I have tried moving the directives to various places in my configuration file, using FCGIWrapper, etc, but nothing I do impacts when my fastcgi'd processes are killed.
Here are the relevant bits from my httpd.conf:
| Code: |
LoadModule fcgid_module modules/mod_fcgid.so
NameVirtualHost *
<VirtualHost *>
ServerName name
Alias /dir/ "C:/path/to/htdocs/"
<Directory "C:/path/to/cgi-bin/">
AllowOverride All

Order allow,deny
Allow from all
SetHandler fcgid-script
</Directory>
<Directory "C:/path/to/htdocs">
DirectoryIndex index.php

Order allow,deny
Allow from all
</Directory>
<IfModule mod_fcgid.c>

# These directives seem to have no effect

DefaultInitEnv PHPRC "c:/path/to/cgi-bin"
</IfModule>

| I found my problem: I needed to set DefaultMinClassProcessCount to 0, to allow mod_fcgid to kill all processes if they were idle, which is what I wanted. |
