[Dovecot] Tbird-DC state problem

[Stewart Dean]

A experienced sysadmin who's doing some guinea-pig use of DC just ran 
into the following situation:
1) He brings up SeaMonkey
2) About 30 minutes later, he's in the middle of some involved 
messaging, mistakenly hits the redX in the top right of the SeaMonkey 
window,  knocking himself out of SeaMonkey.
3) He immediately reinvokes SeaMonkey, all appeared to be OK
Viewed some e-mail and some web page references, tries to send a message 
and then the Send hung for a time with a message "Sending Authenticate 
Info"..after some minutes, a new E-mail window appeared stating the 
"Server reported a timeout". As far as the message, it was apparently 
sent successfully, and saved in the Sent folder successfully.
4) He  calls me in.  I look through the syslog logging.  There is 
nothing in the  syslog  critical stuff...and everything in the maillog 
looks normal.
5) He starts another message, tries to save it to Drafts and that hangs
6) I look more closely at the maillog and see a lot of logins (one a 
minute in some cases, but all appear to have been cleanly executed) plus 
one bunch of disconnected messages with one disconnected in idle in the 
period when the write to the Drafts would have been hung.

Could it be that DC was in the middle of clean up in the initial 
disconnect/reconnect and SeaMonkey came back in the middle of it and one 
or the other's state tables got messed up (or both of them)?   Shutting 
out of SeaMonkey, waiting a minute and reconnecting seems to have gotten 
things working again.  Any comments? Anything I should be looking for?

OTOH, this is the first real problem I've seen in some person-months of 
testing.....
