[Dovecot] Problem with Thunderbird hang, multiple retry to .Sent/.Draft

I have begun havening a problem when sending or when Thunderbird tries 
to write copy to .Draft. Usually only happens when the message is 
longer. While in the Thunderbird editor will say "Copying message to 
Draft folder". It will try indefinitely. The copy is successful but it 
looks like it is believed to have failed so its retried. Same then 
happens when sending. Send happens but then hangs on copy to .Sent. Copy 
works, but apparently is not seen and just keeps getting retried. If you 
let it go hundreds of copies of message end up in .Sent and .Draft. Have 
logs from Thunderbird and rawlog but they are huge and don't want to 
post them to the list until after determining there is no quick answer 
for this behavior.

mail_location: gets an override from userdb SQL lookup. /home/vmail is 
nfs mounted, /var/indexes is is local ext3.

No error messages are logged any place. I think Thunderbird asks for the 
copy and then verifies it. It seems dovecot never confirms they copy 
happened.
