Cpu usage

[avispa987]

Hi everyone,, anyone knows how to limit and monitor what file or why that file is using 100% of cpu?.. i reinstalled all the vps and reinstalled ispcp-omega with its defaults apache configurations...

if anyone knows how to tune apache settings or something.. because with old server configs (debian lenny+ispcp) it worked right for a long time...not too much cpu usage.. but now with debian squeeze + ispcp it just stucks at 100%


thanks in advance
