So ever since Apache moved to modular in version 2 you need to change your tune ups and modification for Apache in MPM instead of directly in apache
So to do this , firstly recompile Apache 2.2.8 in WHM/cPanel with the MPM prefork option enabled ( which is on the last screene of easyapache3 )
And after thats done you need to add your options here , the best way to do it is to add the following lines to httpd.conf
# Server-pool management (MPM specific)
Include "/usr/local/apache/conf/extra/httpd-mpm.conf"
# Various default settings
Include "/usr/local/apache/conf/extra/httpd-default.conf"
Then add the changes you want :
set your timeout
settings etc in
/usr/local/apache/conf/extra/httpd-default.conf
# Timeout: The number of seconds before receives and sends time out.
#
Timeout 150
# KeepAlive: Whether or not to allow persistent connections (more than
# one request per connection). Set to "Off" to deactivate.
#
KeepAlive Off
also
/usr/local/apache/conf/extra/httpd-mpm.conf
StartServers 5
MinSpareServers 5
MaxSpareServers 10
MaxClients 150
MaxRequestsPerChild 0
Then run the distiller to force cPanel to retain the changes
/usr/local/cpanel/bin/apache_conf_distiller –update
