"[notice] child pid XXXX exit signal Segmentation fault (11)" в apache error.log [closed]

Я использую стек Apache/PHP/MySQL.
Использую в качестве фреймворка CakePHP.

Время от времени я получаю пустую белую страницу. Я не могу отладить ее через Cake, поэтому я заглядываю в apache error.log и вот что я получаю:

[Wed Oct 12 15:27:23 2011] [notice] child pid 3580 exit signal Segmentation fault (11)
[Wed Oct 12 15:27:34 2011] [notice] child pid 3581 exit signal Segmentation fault (11)

[Wed Oct 12 22:33:42 2011] [notice] child pid 3774 exit signal Segmentation fault (11)

Что это за ошибка сегментации, и как я могу ее исправить?

UPDATE:

PHP Version 5.3.4, OSX local development
Server version: Apache/2.2.17 (Unix)
CakePhp: 1.3.10
