MailScanner slowwing down

May not be relevant here, but I had a box that slowed down last week. It was
a P4 3GHz unit with only 768MB RAM and I had just upgraded it to the latest
MailScanner download. I was getting a similar load average and lots of
swapping. First off I noticed that the bitdefender update script was hogging
over half the RAM when it kicked in so I turned it off, but since I was at
the machine anyway, I did a yum update (it's running CentOS4). This updated
quite a lot, but also messed up a MailScanner perl dependency, so I
reinstalled  MailScanner from Julian's script and ever since then the
server's been running fine and still with only 768MB RAM.
