next in thread | raw e-mail | index | archive | help
Hello,
I have several machines set up in a testbed network, where each machine
as exactly one control interface. All of the control interfaces are on
the same network. In addition the machines have up to 3 additional
"test" interfaces. The test interfaces are setup as a simple graph and
each pair of interfaces (edge on the graph) is a unique subnet.
The machines are configured to route packets with routed, however routed
on all of the machines crashes constantly. routed runs for some
undetermined amount of time, but it always crashes.
I hope you can help, as this problem is extremely annoying.
Below I have included some information that will hopefully help.
Included: 1 rc.conf, 1 backtrace of a routed.core file, 1 kernel
configuation

Apparently
# vat tries to sync its output off of the soundcard, which is a horrible
