Randomly Apache seems to freak out and eat up cpu usage and overwhelms the server. The amount of daily pageviews is only around 8000 so it can surely handle this traffic. It also seems to happen randomly. Has anyone heard of this happening before and possible solutions?
Some basic server stats: Running WHM/Cpanel latest stable, 4gig memory Xeon(R) CPU X3430 @ 2.40GHz.
Apache: 2.2.17PHP: 5.2.17 w/ eAccelerator
