I forgot to something else unusual too. We are running mrtg on the two 
nodes, and snmpd. mrtg is collecting NIC statistics via snmp, and 
reporting timeouts sporadically. Since I expect UDP traffic over loopback 
to be reliable, I suspect the timeouts are due to delays in snmpd reading 
the interface stats.
