Hello,
I recently upgraded my firewall from a soekris net4501 to a net5501. 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.
