Still no luck with my problem :)
It dies for me somewhere about:

root at accel1:~# netstat -m
208965/585/209550 mbufs in use (current/cache/total)
208432/474/208906/0 mbuf clusters in use (current/cache/total/max)
208432/464 mbuf+clusters out of packet secondary zone in use
0/0/0/0 4k (page size) jumbo clusters in use (current/cache/total/max)
0/0/0/0 9k jumbo clusters in use (current/cache/total/max)
0/0/0/0 16k jumbo clusters in use (current/cache/total/max)
469105K/1094K/470199K bytes allocated to network (current/cache/total)
0/0/0 requests for mbufs denied (mbufs/clusters/mbuf+clusters)
0/0/0 requests for jumbo clusters denied (4k/9k/16k)
0/3/6656 sfbufs in use (current/peak/max)
0 requests for sfbufs denied
0 requests for sfbufs delayed
0 requests for I/O initiated by sendfile
0 calls to protocol drain routines

With panic: kmem_malloc(4096): kmem_map too small: 536870912 total

So there is still memory leak somewhere or i have some rarely
and hardly detectable hardware bug. At least all other squid servers on
this load balancer cluster works fine even under same load as this box
and there is no any mbuf related problems on them.

In any case thank you and all folks for help :)
Happy holidays!
