If you'd said "trouble with mpd" then maybe I'd have looked earlier..
In the poster's defense, the only symptom that started this was this
info from ps:
PID USERNAME THR PRI NICE SIZE RES STATE C TIME WCPU COMMAND
29 root 1 -68 - 0K 16K CPU5 5 196:41 100.00% em0
taskq
So tracking it down to mpd has been a process of elimination in figuring
out why packets absorb so much CPU.
Here is a result of profiling:

50% of time in rip_input???
that's unexpected.. what is the traffic?
also:
I see no netgraph in the profile at all.
did you statically compile it all in at compile time? (you should if
you want to see it)
