New information on this.

My firewall has been up now for some time - 13 days - and no further 
errors/overruns have been reported.  Since I'm starting to learn the 
"ip" command, I just gave the "statistics" option a try.  No overruns 
are reported on any of the network interfaces - yet the "ifconfig" 
command still shows (1) overrun on the one interface.

Why????!?
