APC Object Cache is working very well except for a very annoying issue in the administration panels.
The count (post, comment, plugin, ... whatever the object) in the tabulations are not updated properly. For example, deleting a post do not uptade the count of post nor the trash count on the tabulation.
I'm using a multi site installation.
I move from 3.1.3p3 to 3.1.9 but the issue still here.
