Re: Network often not responding
I little bit frustated after getting no luck with Pyun YongHyeon patch, i run cvsup today and going to see what happen tomorrow. It's happen only on bussy hour/work hour but not on afternoon until morning. it's mean only happen when on maximum/heavy traffic load. I suspected it's error on motherboard or the system. now i'm using 2 ethernet using 2 different catalyst switch and 2 different network. 1st ethernet: em0: Intel(R) PRO/1000 Network Connection Version - 6.0.5 port 0xa800-0xa83f mem 0xfeaa-0xfeab,0xfea8-0xfea9 irq 18 at device 3.0 on pci2 em0: Ethernet address: 00:e0:81:31:af:ca em0: [FAST] 2nd ethernet: xl0: 3Com 3c905B-TX Fast Etherlink XL port 0xa880-0xa8ff mem 0xfeafec00-0xfeafec7f irq 19 at device 7.0 on pci2 miibus0: MII bus on xl0 xlphy0: 3Com internal media interface on miibus0 xlphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto xl0: Ethernet address: 00:10:5a:0d:c1:45 Best regards, Thursday, August 10, 2006, 8:08:45 PM, Dominic wrote: Stanislaw Halik wrote: On Wed, Aug 09, 2006, Dominic Marks wrote: Aug 9 15:09:16 cache kernel: xl0: transmission error: 90 Aug 9 15:09:16 cache kernel: xl0: tx underrun, increasing tx start threshold to 120 bytes dc%d: TX underrun -- increasing TX threshold The device generated a transmit underrun error while attempting to DMA and transmit a packet.

Network often not responding
Hello, I have squid cache server using: MB Tyan Tiger K8W/S2875 Dual Opteron 246 4 GB DDR, connected to cisco catalyst. Freebsd AMD64 6.1-Stable sometimes network down and up again on uncertain condition i've tried change network card and disable onboadr gigabit ethernet, work good for a days then it happen again. Then i try to move another port on catalyst switch, it's same. When network not responding connecting using cross-cable not work too. it will up again 5 minutes later or more. I can't find any relevan error on /var/log/message except something like this: Aug 9 15:09:16 cache kernel: xl0: transmission error: 90 Aug 9 15:09:16 cache kernel: xl0: tx underrun, increasing tx start threshold to 120 bytes anyone experienced something like this ? ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to [EMAIL PROTECTED]

Hello, right now, i'm using 3com ethernet: xl0: 3Com 3c905B-TX Fast Etherlink XL port 0xa880-0xa8ff mem 0xfeafec00-0xfeafec7f irq 19 at device 7.0 on pci2 miibus0: MII bus on xl0 xlphy0: 3Com internal media interface on miibus0 xlphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto xl0: Ethernet address: 00:10:5a:0d:c1:45 onboard ethernet which disabled via BIOS was: Intel 82541E1 GbE Average traffic is 10-15Mbps on bussy hours, and connected client average 1000 #netstat -n | grep EST | wc -l # 780 I really confused, i don't have any other Freebsd AMD64 system installed, but other with i386 system never got any problem like this.
