I am implementing the apc on a shared server that currently has 1000 sites (using wordpress, moodle, etc.). I'm Looking for the admin page, and I see "Cache full count" is growing rapidly. I've tried increasing the value of "apc.shm_size" reduce value "apc.ttl" increase the value "apc.shm_segments" but I can not resolve this issue. What am I doing wrong? I'm putting down some information:

apc.ini:

extension=apc.so

apc.shm_size = 256

apc.enabled = 1

apc.ttl = 300

apc.user_ttl = 300

Ubuntu: 12.04

PHP: 5.3.10

APC: 3.1.7

Server has 16GB memory

Limit share memory: 256MB
