Any idea what kernel parameter I should adjust to address the above error
message?  I'm running 2.2-stable as of Saturday morning, and after 1 day of
uptime I got the above error, with loss of network connectivity for ~5
minutes, but no reboot.  It's a very public machine and has been a target
for DoS attacks in the past - so it's possible a DoS attack caused the
above, if so I'd be curious to know what kind of DoS attack.

If you need more info about existing kernel config settings let me know.
The most relevant ones are probably:

maxusers        512
options         IPFIREWALL
options         IPDIVERT
options         NMBCLUSTERS=4096        # mbuf clusters at 4096
options         MAXMEM=262144           # Make me one with everything!

Thanks...

	Brian
