New Comment:
Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read
http://bugs.php.net/bugs-generating-backtrace.php
for *NIX and
http://bugs.php.net/bugs-generating-backtrace-win32.php
for Win32
Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.
It'd help to know what the code is doing too. And what changed when the segfaults started
happening.

Description:
------------
When I start the server under load and it segfaults every 5 mins and this rate increases until after
a few hours it's several times a second.
