Tell me how to find the leak.
Has a brand piece of iron, it spins a couple of sites on Joomla, Gallery2, DokuWiki, phpMyAdmin, Munin
From time to time crashes with the same entries in the log:
[notice] child pid 22048 exit signal Segmentation fault (11)
I tried to put apache2-mpm-itk (have) — you get basically the same thing:
[error] child died with signal 11
In apache2.conf put LogLevel debug in php.ini put error_reporting = E_ALL & ~E_DEPRECATED
but nothing in the logs interesting, sometimes swears on Undefined php variable and the lack of files and all.
It seems that the memory is leaking, but can't figure out who is to blame.
A little bit about the system:

Installed php-apc 3.1.3p1-2, tried to update to 3.1.4, and 3.1.5 — no difference.
The whole set of soft — Repov, he didn't pack anything.
UPD: the ambush was in a bunch of Joomla + APC. Demolished APC, configured nginx+apache2+eAccelerator — some days flight normal. The software upgrade has decided not to pursue for experimental purposes.
