So anything that is using a generic 2KB of memory. Tricky to track down :-(. I would look at the next few entries to see if there is a good clue about what system might be worth a closer look (largest amount of things active, or anything else not being released). Mostly it is I/O using the various Buffer's, but some other things do as well. > >>> cache_dir rock /var/spool/squid3/rock 1024 max-size=32768 >>> #cache_dir aufs /var/spool/squid3 8192 16 256 min-size=32769 >>> >>> are those correct values?

Squid-3.5 'large rock' feature adds slots as needed to fit the extra meta bytes. So 32KB is no longer an absolute limit.
