You probably have a Max Children setting that's too high. Unlike Apache
(whose child worker processes don't do anything when the machine is idle,
and will happily page out), MailScanner is continuously active scanning
the incoming queue for new messages. Also unlike Apache, MailScanner's
child processes are big and don't share much of their memory -- on my
setup each child uses 20MB. I would run with Max Children = 2 on your
machine.
