Shared memory cache in official Squid releases does not support storing objects larger than 32KB. This limitation is unrelated to cache_dirs in use. >> What do two cache manager mgr:storedir queries, sent a few hours apart, >> show? Does the memory cache grow?

It indicates that the shared memory cache is 58% full and can accept more entries. What do TWO cache manager mgr:storedir queries, sent a few hours apart, show?
