Easiest thing is to obtain a core dump; see the man page for 'ulimit', 
check
'/etc/login.conf' and the apache directive for this.

Otherwise - if it happens a LOT - you can run (from screen if needed)

	gdb /usr/local/sbin/httpd -X

it will then run single process/thread mode; and if there is a segfault 
you'll
inmediately see the culprit. This is generally too slow for a production
server; but will easily handle hobby sites.

Given your setup my guess is some PHP5 plugin (I had similar issues
until I fixed/recompiled gd).
