How recent did you install it?  My initial thought is to disable APC.
The 3.1.10 version released last week fixed a few bugs that caused
crashes with PHP 5.4
http://pecl.php.net/package-changelog.php?package=APC&release=3.1.10
Note this version of APC incorrectly reports itself as 3.1.9
(https://bugs.php.net/bug.php?id=61695)

If this doesn't help, construct a small reproducible testcase and log
a bug at https://bugs.php.net/report.php
