squid-ntlm pre-prod report

I have a squid-2.5-ntlm in a pre-production testing stage, and
it's faring quite well.

I'm getting close to the 11 million hits mark over 5 days, only problem
has been 1 stuck NTLM helper process (out of 10, and it's been
more-or-less recovered).

Tonight I'm going to schedule-restart it, since it's grown quite huge:

        memPoolAlloc calls: 1309902274
        memPoolFree calls: 1307691362

Now, the number of swapin and swapouts is pretty low, which leads me to
think
about big chunks of leaked memory (at least PAGE_SIZE big).
Notice: I'm using nullfs storage, so it's not StoreEntries.
Idle pool limit is 10 MB, and MemPool allocations account for 62 Mb total.

If anybody wishes me to perform any diagnostics or something, s/he has 6
hours :)
