Hi,
I am maintaining a large-volume HTTP server. It is with one em0 gigabit NIC, and running apache(or thttpd) for users to download relatively big(>200k) files. I started this service using 4.5R. It shows about 500Mbit/sec performance(the server is Pentium III 1G, 1G RAM, 36G SCSI HDD). Server load was very high(>200) but I heard it's characteristic of apache server and I decided to upgrade to recent system and use thttpd instead of apache. 2 days ago I updated the system to 4.6-RELEASE. Whether or not using apache or thttpd, under some traffic(about >150Mbit/sec), it shows "watchdog timeout" repeatedly: Jun 16 11:36:18 gigatest /kernel: em0: Link is Down Jun 16 11:36:18 gigatest /kernel: em0: Link is up 1000 Mbps Full Duplex Jun 16 11:40:49 gigatest /kernel: em0: watchdog timeout -- resetting Jun 16 11:40:51 gigatest /kernel: em0: Link is Down Jun 16 11:40:51 gigatest /kernel: em0: Link is up 1000 Mbps Full Duplex Jun 16 11:40:51 gigatest /kernel: em0: Link is Down Jun 16 11:40:51 gigatest /kernel: em0: Link is up 1000 Mbps Full Duplex Jun 16 11:44:23 gigatest /kernel: em0: watchdog timeout -- resetting Jun 16 11:44:24 gigatest /kernel: em0: Link is Down Jun 16 11:44:24 gigatest /kernel: em0: Link is up 1000 Mbps Full Duplex Jun 16 11:50:28 gigatest /kernel: em0: watchdog timeout -- resetting Jun 16 11:50:29 gigatest /kernel: em0: Link is Down Jun 16 11:50:29 gigatest /kernel: em0: Link is up 1000 Mbps Full Duplex Jun 16 11:50:30 gigatest /kernel: em0: Link is Down Jun 16 11:50:30 gigatest /kernel: em0: Link is up 1000 Mbps Full Duplex Jun 16 11:50:30 gigatest /kernel: em0: Link is Down Jun 16 11:50:30 gigatest /kernel: em0: Link is up 1000 Mbps FullDuplex Jun 16 11:50:30 gigatest /kernel: em0: Link is Down Jun 16 11:50:30 gigatest /kernel: em0: Link is up 1000 Mbps Full Duplex I updated em0 driver to 1.3.8 from Intel webpage, but it no helps. Can you suggest some advice? If not, I have to back to 4.5R-p5. -- +++ Any opinions in this posting are my own and not those of my employers +++ CHOI Junho [sleeping now] <http://www.kr.FreeBSD.org/~cjh> [while sleeping] <cjh @ kr.FreeBSD.ORG> <cjh @ FreeBSD.ORG> <cjh @ wdb.co.kr> Korea FreeBSD Users Group <www.kr.FreeBSD.org> Web Data Bank<www.wdb.co.kr> To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-net" in the body of the message
