php5-fpm create new session id in every refresh

February 3, 2015 605 views

I have Magento server(ubuntu) with ngix and php-fpm. Sometimes the server create new session id in every refresh. Other time it's working perfectly. Once I restart my php5-fpm service it works again.

Is there something to do with Memory of the system?
