I have installed PHP as an Apache module. I have had prefork running all this while. I've read that worker would consume less memory while offer higher performance]1. So, I've edited /etc/sysconfig/httpd and uncommented:
HTTPD=/usr/sbin/httpd.worker
and restarted Apache.
Last Friday (10/7/2011) we started having httpd.worker processes grow from the
typical 10-15M memory reserved to 10G+ (gigabytes) in a matter of 1-2 minutes. This obviously brings the server to a halt as it starts swapping etc. We have to reboot the server in order to get it running again.
Hi,
We recently tried switching one of our servers over from the default MPM prefork to worker. The savings in memory were really surprising but we have no experience of tuning with worker. Can anyone give us a rough idea of any changes we could make to the default worker setting? This server has 8 cores and 12GB ram also running varnish.
Please help with some ideas about this Apache server crash:
Here is my MPM config and errors
<IfModule prefork.c>
StartServers 5
MinSpareServers 30
MaxSpareServers 40
ServerLimit 950
MaxClients 950
MaxRequestsPerChild 2000
</IfModule>

I need to set up my apache HTTPd to handle 100.000-300.000 users in 3 minutes. I want to use PHP-FPM and (maybe) worker module. What else is necessary to handle so many requests? Which default settings in httpd.conf should I change? CPU is fast, big RAM and communication between user and server (HTTPS) will be low. Every answer will be very appreciated.
I'm newbie on VPS configuration.

For years I have been using the mpm-prefork module as it was my understanding that this was the preferred worker for Apache 2 and 1.3.
Now I will be installing some fresh Apache servers and will be using the newer 2.4 version, with which the event based mpm which uses epoll/kqueue.
I know in the last few years event based systems have become all the rage (e.g.
