Ah. 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.
will be glad if this helps...

are those correct values? (bug 3411 says something about 256B metadata)
Those 256 Byte will matter for Squid-3.4.
doesn't it for later squid versions?
Nope :-). Squid-3.5 'large rock' feature adds slots as needed to fit the
extra meta bytes. So 32KB is no longer an absolute limit.
will it waste whole slot or does it already support smaller chunks?
