I've seen this too. I'll walk by the server, see all the lights on, scratch my head, run top and there's httpd working very hard at something.
Whatever it is, it's very intermittent and seems to coincide when I am truly handling lots of resource requests, but there is obviously something else going on. Whatever processes they are, they must be nice because I can't discern a slowdown in general responsiveness. Then as soon as it started, it stops; maybe an hour or two though. About once a week I stand in front of the server and compliment it on its disposition, work ethic, etc. and it seems to be satisfied. :-/ John On Jan 19, 2011, at 12:50 PM, Tim Worman <li...@thetimmy.com> wrote: > I have an app that, during the course of normal usage, is starting httpd > processes on the server that instantly hit 100% CPU usage of one core.
