I periodicaly see php-fpm errors (usually every 3-5 hours it crashes)
Jan 22 15:17:15 DS2152 kernel: pid 16212 (php-fpm), uid 80: exited on signal 11 (core dumped)

I cant find how to reproduce the problem, cant see any regularity.
It can be reproduced on php 5.5.8. I've tried it on php 5.5 snapshot and it appears.
