mod_fcgid not using multiple php interpreters for concurrent requests

I have the following problem with mod_fcgid on apache with php.

Everything runs without any errors but all my requests are processed by one php interpreter, even when I set PHP_FCGI_CHILDREN>1 and there are multiple php interpreters. FcgidMinProccessPerClass also does nothing.

I discovered this using a sleep call into a test script.

Here is my config:

/usr/local/cpanel/cgi-sys/php5

exec /usr/bin/php 

/home/usercp/public_html/cgi-bin/php.fcgi

#!/bin/sh export PHPRC="/home/usercp/public_html/php.ini" export PHP_FCGI_CHILDREN=2 export PHP_FCGI_MAX_REQUESTS=10 exec /usr/local/cpanel/cgi-sys/php5 

/etc/httpd/conf/php.conf

# Fastcgi configuration for PHP5 LoadModule fcgid_module modules/mod_fcgid.so FcgidMaxRequestsPerProcess 500 FcgidMinProcessesPerClass 1 FcgidMaxProcessesPerClass 10 FCGIWrapper /usr/local/cpanel/cgi-sys/php5 .php5 FCGIWrapper /usr/local/cpanel/cgi-sys/php5 .php4 FCGIWrapper /usr/local/cpanel/cgi-sys/php5 .php FCGIWrapper /usr/local/cpanel/cgi-sys/php5 .php3 FCGIWrapper /usr/local/cpanel/cgi-sys/php5 .php2 FCGIWrapper /usr/local/cpanel/cgi-sys/php5 .phtml
