Actually traced the issue down to a device (possibly a 2948 Switch) sending
a stream of UDP packets causing the CPU to peg. Filtered all UDP and
everything calmed down. In the process of tracing down the culprit. Thanks
for everyone's input.

Check to see if you have a multicast (or several)
stream going through. We are seeing the first signs of
a bug on ours where it appears that all packets are
written to MLS and process switching.
