Still no luck with my problem :) It dies for me somewhere about: root@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 (current/cache) 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 allocated 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! > > Cheers, > -- > Xin LI <delphij@delphij.net> http://www.delphij.net/ > FreeBSD - The Power to Serve! > -- ====================================================================== - Best regards, Nikolay Pavlov. <<<----------------------------------- ======================================================================
