You don't mention the specification of the server you're using, and I
don't know enough about Compaq harware to guess.  But if the problem
was caused by having excessive numbers of spamd processes running,
then using "-m 2" is certainly going to help.

I've seen this on a low-end Sparc we use at work for mail -- on odd
occasions it would be deluged with messages which it would start to
process.  The box was running sendmail with a queue-runner kicking off
every 2 minutes.  Once it got up to 4 concurrent spamds running, the
system would start swapping and slow right down.  It was only just
about usable -- fortunately it didn't actually need to be rebooted.
The mail admin has since added "-m 3" to spamd and so far I haven't
seen this happen again (though it's only been running a week with 
"-m 3" so far).

Depending on how powerful the box is, and how much other work it's
doing, you might be able to slowly increase the "-m" value -- if it's
set too low you run the risk of having a mail backlog build up with
the result that mail gets delayed.
