OK - I didn't know that I might be reporting something new. Here's some 
more details. I leave my computer on at might (Windows XP) and it's 
worse in the morning when I wake up. Thunderbird's checks the email 
every 1 minute and it's set up to check several IMAP folders. I'm 
running the latest Thunderbird release as will as the latest Dovecot 
(not the beta versions).

In the morning it is as if it can't access dovecot at all. I get an hour 
glass as if it is waiting for something that's never going to respond. 
But if I shut down Thunderbird and restart it then everything works 
normal for a while.

My server is doing a lot of work but the load levels are low. Running 
Fedora 8, dual core AMD 6000+ processor with 8 gigs of ram.

My experimenting with adding more authentication processes seems to help 
but I could be fooling myself. That's why I'm experimenting to try to 
figure out what's making it slow.

Like someone else said, I saw something like this happen with several 
RCs but at the time I thought it was MBOX related. I'm not using Maildir.

Hope this extra info helps.
