I've been getting tons of the following error appearing in my Apache error.log.
PHP Warning: apc_store(): Unable to allocate memory for pool. in /home/username/www/mysitedir/wp-content/plugins/w3-total-cache/lib/W3/Cache/Apc.php on line 55
I have NewRelic enabled and this error appears to arise from requesting just about any template including index.php, single.php, etc.
I've increased the apc.shm_size to 256M in php.ini and that hasn't solved the issue.
Any tips on what I should attempt to debug from here?
P.S. The submit bug report feature just shows the loading spinner indefinitely.
