I know that there is already a discussion about this here and a closed issue here .
The problem is that for me it crashes completely random, without errors in my logs and the only solution is to restart php fpm. I have 2 environments + dev environment. In staging and dev env, it is working without problem. In production, I get this error. All the environments have this config:
Phalcon 1.3.4
Nginx 1.6.2
PHP 5.5.18-1+deb.sury.org~trusty+1 (cli) (built: Oct 17 2014 15:20:47)

The only difference between staging and production is that in staging I enabled phalcon debug listener and I always recompile Volt templates.
Most of the answers from google (because other people that are using other framweroks and configurations have this problem) are related to write permissions, and it's not my case.
Any suggestions will be much appreciated. Thanks.
