[humble linuxer]

one of httpd on my server is crashing with segmentation fault.
Any ideas as to why this may be happening?

Below is the content of the log file.

Perhaps bad memory? I'd run memtest86 on the box for a few hours to see if it generates any errors.

You aren't running PHP on a non-prefork version of Apache2, are you? I think it was seg faulting on me when I tried to do that because PHP is not threadsafe.
