It is possible that the problem is a scheduler misconfiguration. The
default (200 channels for a few smtp domains) is pretty optimistic.
I have a mailing list running on zmailer, and if a couple of messages
to the list were received by zmailer, the scheduler (not the smtpserver)
would spawn a number of smtp processes which will consume all swap space.
After I realized what the configuration means, I trimmed down the number
of channels to a much lower number and have not seen the problem since.
