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. This can happen multiple times during times when the app is under heavier load. After some time I can have many httpd processes where TOP reports each using 100% of a core. When I try to log into the app and poke around to try and reproduce the issue, I am unable.
Does anyone have any pointers as to how I can try to narrow down specific requests or conditions that may be causing these processes to be spawned?
This app was just recently moved to MOSXS/Intel. Previously it ran on MOSXS 10.5/PowerPC and I didn't see the same problems there. Truthfully though, it could be caused by some other change I made since but I thought the architecture could be an important factor if someone else has seen similar symptoms.
