   Been getting a lot of these in my apache error logs regarding APC & W3TC.

   [Thu Dec 02 03:59:32 2010] [error] [client] PHP Warning: apc_store(): Potential cache slam averted for key 'w3tc_039d02f8a4c19d927cf3aae9734613fa_object_b32188885056bd3a650b6a521698b57c' in /home/**User**/public_html/wp-content/plugins/w3-total-cache/lib/W3/Cache/Apc.php on line 40

   Any ideas?

   Try increasing apc_shm_size to around 128M

   @Sujay, did @c3mdigital's suggestion work for you?

   I believe apc_shm_size is not relevant to this problem, it's most likely due to a reported bug in APC. I always had this problem on my server and after upgrading APC to the newest version (3.1.6) it appears to be solved.

   You should look at your APC statistics. Most likely you reached 100% fragmentation.
