I am getting so many of these error that I cannot get reliable throughput anymore. The system has 2 Lynx 4-port cards (de0-de7), P1-233, 196MB RAM. Was running 2.2.2-RELEASE without any problems. Underflow problems reported were: de0: abnormal interrupt: transmit underflow (raising X threshold to 96|256) de0: abnormal interrupt: transmit underflow (raising X threshold to 128|512) de0: abnormal interrupt: transmit underflow (raising X threshold to 160|1024) After swapping boot drives to one running 2.2.8-RELEASE, I am now receiving: Oct 25 11:14:29 starfish /kernel: de0: abnormal interrupt: transmit underflow Oct 25 11:15:00 starfish last message repeated 24 times Oct 25 11:17:01 starfish last message repeated 135 times I was getting a lot of collisions so I set de0 to 10baseT full-duplex and my HP Procurve switch to full-duplex and all collisions disappeared. However I still am having problems and I see IN and OUT frame errors. Here's some output: starfish# netstat -i | grep de0; sleep 5; netstat -i | grep de0 Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll de0 1500 <Link> 00.c0.95.f0.3a.34 502072536 2258970 504489650 1902369 30311942 de0 1500 205.240.25 starfish.pond.n 502072536 2258970 504489650 1902369 30311942 de0 1500 216.36/26 pcncore-gw.eug. 502072536 2258970 504489650 1902369 30311942 de0 1500 216.36.3 pond-gw.pond.ne 502072536 2258970 504489650 1902369 30311942 de0 1500 <Link> 00.c0.95.f0.3a.34 502075518 2259002 504492947 1902376 30311942 de0 1500 205.240.25 starfish.pond.n 502075518 2259002 504492947 1902376 30311942 de0 1500 216.36/26 pcncore-gw.eug. 502075518 2259002 504492947 1902376 30311942 de0 1500 216.36.3 pond-gw.pond.ne 502075518 2259002 504492947 1902376 30311942 I'm not sure what to do now. I have replaced the Ethernet cable and moved it to other ports on the switch. All my de? ports have errors, just not as many because this is my primary interface out the the Net. Any Help??
