XF 1.1 APC Affecting AdminCP

#1
I have observed, what seems to be, a unique issue for XenForo AdminCP interface with the enabling of the APC Backend Cache.

Apparently, the AdminCP's login interface is accessible. After punching in the login credentials, the XenForo logo will run through the AutoLoader process before throwing me back to the login interface again.

In order to break out of this cycle, I have to disable the APC cache option in the config.php file. I have tried to use the apc.filter variable to exclude out the AdminCP file but to no avail.

Is there anything that I may have missed out on?

Are you putting sessions in the cache? Then that means your APC cache is full (and you having setup LRU purging). Disable putting sessions in APC, make sure the memory available will never be filled, or enable LRU purging (apc.ttl, though this may not be perfect).
