 * I’m curious how APC works with memory. On one host where object cache is used
   a lot the server can max out on 8GB memory. The hosting is seeing that object-
   cache.php is trying to allocate more then 512MB of memory. PHP memory_limit and
   apc.shm_size are both 512MB.
 * It seems that APC cache is always loaded to PHP and then set back. Is that correct?
   I’m trying to understand how to fix it.
