I try to monitor the logs as much as possible, but I've yet to see
anything related to this problem.

With MailScanner running, around 1.5.  With only sendmail with
spamass-milter running, around 0.5.

There's a gig of ram installed (I earlier said a gig and a half, I was
mistaken).  Quad Xeon 500MHz cpu's.

Again, without MailScanner running, I've been able to get over a week of
uptime.  With it running, it never goes more than a day or two.  And
that is with Virus Scanner = no and Spam Checks = no.
