This is a box sitting on the end of a cable modem in my basement
office. it doesn't see a large network load, although I'm blocking
about 900 spam attempts per day (the same two bozos with forged
addresses keep retrying every five minutes, and I keep 550-ing them.
Now, it could be that my ISP is retrying to send these messages,
which wouldn't surprise me :-( ).
By tonight, I expect to see around 500 mbuf clusters in use, and a
comparable number of mbufs in use. By late tomorrow, it will be time
to reboot. :-(
