Hi All
I am trying to troubleshoot a problem that's been bugging me for several months. About once or twice per week my IMAP server seems to get in a state where no connections are possible (Thunderbird hangs at "Connected to <server>").
Restarting dovecot completely fixes the problem, until it occurs again, hours or days later.
I caught the problem today after I rebooted my server, and monitored the running processes while attempting to connect. After each connection attempt, the number of imap-idle processes running decremented until none at all were running.
Before the final imap-login process died, I attached an instance of strace to it - results here:

I am running Dovecot 1.0_rc15 on a Gentoo server. It's a vmware virtual server - mentioning this now just in case, but I'm confident that's not anything to do with it, no other services are having any problems that I am aware of.
I am using TLS and Maildir.
I don't know enough about how dovecot is supposed to work, so I would appreciate some help in diagnosing this problem!
Cheers, James
