I wanted to let you know that the problem has been resolved. Following Robert's advice i exported the contents of the mailboxes.db file by running: ctl_mboxlist -d > filename , then I removed /var/imap/mailboxes.db, /var/imap/deliver.db, and /var/imap/deliverdb/* . I then reimported the dump file by running ctl_mboxlist -u < filename. Immediately all the queued mail started to be delivered and all the rest of the problems dissapeared.
It seems as though a corrupt deliver.db or mailboxes.db file will cause the majority of lmtp processes to sleep in an active state (bringing delivery to a virtual halt), which also quickly maxes out server resources, eventually causing the server to stop allowing users to login/read mail as well.
Anyway, thanks again to everyone for helping. Especially thanks to Robert.
Sincerely,
Lee

That's odd. I can't duplicate this locally, I have (in the SERVICES
section of cyrus.conf):
imap cmd="imapd" listen="imap" maxchild=2
And I can now only launch 2 imapd processes, yet the remainder of my
processes are unaffected. So, I don't know why this won't work for
you.
