Do you have configured a connection limit per user?

Thunderbird tends to use plenty of connections simultaneously, if multiple 
actions are going on. There was an advice on the Courier list (I used once 
upon a time) to drop the default of 5 simultaneous connection to three, 
which worked out better those days.

We have three users accessing the same mail account all time, but I did 
not hear about this problem with Dovecot v1.0, yet. There is one annoying 
issue, that Thunderbird updates the state of messages (Read / Answered / 
Flagged) very slowly.

Very occasioanlly we had problems that Dovecot does not accept new 
connections at all. Already existing ones work with no visible problem, 
the dovecot auth process is handling stuff (one can see while tracing it). 
There had been no signs of this problem for several months now.
