The problem is there are times that the server stops on working no apache processess in the background. its just plain like this.

and then my xfilesharing website and cpanel/whm wont
load and so my embedded videos. I dont know how to trace
the problem and whats causing this. If you guys know please helpme.
usually the problems lasts for like 10 minutes and it
backs to normal on its own. those down times, its very important to me.

all advises are appreciated. sorry for my bad english.

seems like apache crash and cpanel restart your crashed apache.

Check System logs, Apache Logs and all others.

I dont use WHM/cPanel for my servers, because it use more resource and it have own complicated for error tracking etc.

My advice for 1 site hosting, install servers one by one and check/control manualy.

fixed by raising max clients.
