Issue APC stored variables not persisting

Peter Downes

Basic Pleskian
Hi Forum

We have a VPS (OS ‪CentOS 6.5 (Final)‬ / Plesk version 12.5.30 Update #48).

It hosts a website with a large database table and have installed APC to help speed it up.

Unfortunately the apc stored variables not 'persisting'. They are sometimes stored but are then, on refresh lost only to reappear a few refreshes later. The result is a very high MySQL CPU Usage (50% to 90%).

This problem followed the website from another server to this one.

However Plesk is the control panel on both.

Before we move it again we wondered if anybody had a similar experience and found a solution?

Many Thanks
 
The problem may be related to used PHP handler. I suppose that you use FastCGI?
Have you tested this issue with another PHP handlers?
