Take the 2-minute tour ×  Every hour or so an Apache child
process seg. faults on our web server. We are running a non-
threaded PHP 5.2.17 Apache module with Apache prefork MPM. I
have run httpd with a few core dumps, gdb and this .gdbinit file
from php's github repo, typing this command into gdb for each:
dump_bt executor_globals.current_execute_data  With no
experience with gdb or the inner-workings of the php
interpreter, I can't make anything from the results.
