From: Vladimir Kutakov <v...@ashmanov.com> To: bug-follo...@freebsd.org, v...@ashmanov.com Cc: Subject: Re: kern/155597: [panic] Kernel panics with "sbdrop" message Date: Thu, 24 Mar 2011 12:35:34 +0300 We are looking into this problem a bit. The panic is reproducible easily by means of big http trafic. We ran apache benchmark on 3 next servers: ab -c40 -n20000000 'http://thehost/somesmallfile'. After just some minutes panic occurs. However, after decreasing hw.igb.num_queues to 4 (default value is 8), it occurs only after 2 hours. Finally, the server with hw.igb.num_queues=1 works good already 7 days. It seems that some problem happens during parallel tcp processing. -- WBR, Vladimir mailto:v...@ashmanov.com _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
