apache failing for some reason
httpd is showing very high cpu usage but rarely affects the overall load. Server runs fast even at peek but still fails. It also seems that most my CPU stays idle for some reason and never gets used.
A typical TOP looks like this
20:33:43 up 12:42, 1 user, load average: 0.45, 0.56, 0.98
