I only have about 10 email users on my server. It's a dedicated server, and only the employees use it for email. It's a dual proc, 4gig machine, running latest whm/cpanel. We all use imap to check our mail, and lately i've been getting a lot of messages like:

imap failed @ Wed Mar 26 17:28:35 2008. A restart was attempted automagically.

These are mailed to me via cpanel, but I can find no evidence of what is causing this in the maillog or messages log files. Does anyone have any clues where I should start looking? Or any config options I can play with?

Cheers,
