Virtual Memory Consumption of Cyrus IMAPd

Not sure about RHEL, but on Fedora Core 1 the saslauthd process eats tons of
swap until eventually there's no memory left. Great fun! This of course stops
cyrus from being able to process imap and pop logins (if you're using 
for authentication). A simple restart usually fixes this particular problem.

This may or may not be related to what you're seeing, but I figured I'd throw
this out there.
