Questions, is PHP run through dso or statically compiled in?  Is the httpd
child core dumping? If so can you get a stack trace off the core file? Are
you using persistant connections? Have you tried running PHP in cgi mode
(like on a test server on a different port) and does it still happen
there?

We may need to tweak the code a bit to see what is going...Let me know
