[Dovecot] Stale imap processes

[Fran Fabrizio]

Anyone have any theories or experiences as to why for a certain user, 
some of his imap processes hang, and stay around for days and days?  He 
just reported that his Thunderbird was timing out when trying to open 
folders, I looked on the server, and he had 3 old imap processes from 1 
week+ ago.  I killed those and his performance immediately improved.

He checks mail with Thunderbird > 1.5 from both Win and Linux, 
Squirrelmail webmail, and pine.  Of those, pine is the only one that is 
somewhat rare around here - any specific problems with pine's imap 
client code that anyone knows about?

We have been using the dovecot-1.0-0.beta2.7 rpm for Fedora Core 5, I'm 
updating to 1.0-0.beta8.2.fc5 to see if that helps, as well.  Just 
curious if anyone else has seen this lately.

Thanks,
Fran
