[TriLUG] Apache segfaulting when executing PHP

[Paul G. Szabady]

Brian,

I am currently fighting a similar battle, however it's only a specific
page that cause the seg fault.

Take a look at http://httpd.apache.org/dev/debugging.html

Also, take a look this recent thread on TriLUG for some tips I rec'd on
dumping core, starting ~Mar 5, 2007. "Apache: Segmentation fault errors"

Good Luck!
