If it is OPcache related, try using OPcache from https://github.com/zend-
dev/ZendOptimizerPlus. This has various fixes that aren't yet in PECL.

I installed OpCache from this link:
http://pecl.php.net/package/ZendOpcache/7.0.1
I'll check if it will be reproduced without opcode cache.

Where did you install opcache from?
Does the crash happen without opcache?

i'sorry we're using php-5.4.10 because not all modules can run on 5.4.14
