Massive Problems (lmtp, db corruption) - Ahh!

[Joe Finkle]

Hey All,
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
