I run a busy website algebra.com on a CentOS server.

Occasionally, apache processes crash with a "segmentation fault".

I often get 140+ object requests per second, so isolating which request caused segfault, by looking at logs, is not practicable.

I want to know if I can at least isolate the cause of the problem to a URL (webpage) that caused it to crash. A stack dump would be ideal, but if I can get URL and parameters, that would already be very nice. 

Any suggestions?
