As = part of this process I update my freebsd sources to CURRENT as of = 11/13/2009 1300 GMT. Once the new box was up and running I noticed some = odd output in the logs: Nov 13 18:30:19 gate kernel: dummynet: OUCH! pipe should have been = idle! Nov 13 18:30:34 gate last message repeated 15 times My dummynet configuration looks like this: fw=3D'/sbin/ipfw -q' $fw pipe 10 config bw 950Kbit/s $fw queue 10 config pipe 10 weight 100 $fw queue 20 config pipe 10 weight 1 $fw add 6100 queue 10 tcp from any to any tcpflags ack iplen 0-80 out = via $oif $fw add 6110 queue 10 udp from any to any iplen 0-80 out via $oif $fw add 6120 queue 20 tcp from any to any \{ not tcpflags ack or not = iplen 0-80 \} out via $oif $fw add 6130 queue 20 udp from any to any not iplen 0-80 out via $oif I am running SCHED_4BSD with a HZ of 1000. Otherwise the kernel is = mostly a stripped down version of GENERIC. I can post the full config = if it would be relevant. I was previously running a HZ of 250, but I increased it to 1000 to see = if that was causing the problem. It did reduce the number of OUCH = messages, but did not get rid of them completely. Does anyone know what could cause these messages? Should I be = concerned? As far as I can tell the network is working fine in spite of = the log output. Thanks. - Ben=
