User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:22.214.171.124) Gecko/20070718 Fedora/126.96.36.199-1.fc7 Firefox/188.8.131.52 Build Identifier: "184.108.40.206pre (20070926)", "220.127.116.11", and others I'm running Thunderbird with one IMAP account against an Exchange server (exchange.foo.bar in the log). I've seen this with at least 18.104.22.168, up to 22.214.171.124. After some period of time, between five minutes and several hours, Thunderbird will stop loading new messages. Any messages that are marked as new but have never been read cannot be viewed. Only a restart will fix it. Both the attached log and a wireshark trace shows that Thunderbird is doing up to 700 "UID fetch 53244 (UID RFC822.SIZE BODY.PEEK)" per second. There seems to be no usage pattern that triggers this behavior, although it does seem to happen after a period of idle time, where the idle time could be as short as one minute. Reproducible: Always Steps to Reproduce: 1. 2. 3. I'm running Thunderbird on Fedora 7. A colleague is running it on Ubuntu against a similar Exchange server (same company, different server) and is seeing similar behavior. Also note that Thunderbird is not the only client accessing the account, as there is a BlackBerry server that is also manipulating the email (when I use my BlackBerry, it talks to the BlackBerry server which in turn talks to Exchange). However there is no pattern, this behavior occurs when I don't touch my BlackBerry as well.
IMAP log when Thunderbird hung.
Which version of exchange server 2000/2003/2007? Check also if latest version of Service pack applied or not. Sounds like bug IMAP implementation of exchange server. Also try latest TRUNK build of TB and see if it happens for you again.
If you are running exchange 2000 here is link for ya http://support.microsoft.com/kb/320432/en-us
Nikolay: not sure if that URL is relevant; he doesn't say he's using SSL. In fact he can't be, if he's sniffing the traffic using Wireshark. Michael: are you able to answer Nikolay's question? An engineer should look at this log. Confirming. Gerv

Ever confirmed: true
I tried many versions of Thunderbird including several 2.0 trunk builds, but all behaved the same way. I don't know what version of Exchange we were running, and our IT dept. isn't very helpful in that regard. However we were not using SSL. It would not surprise me at all if this was an Exchange IMAP problem (it's buggy at best), but again no control over that bit. I'm unfortunately not able to comment any further, as we've all moved to running Mac's now, and I'm using Entourage as my main mail client (sorry, need Calendar integration...). I no longer have a Linux system that is capable of running Thunderbird. All I can say is that this was reproducible and happened with at least 3 different people in my department. cheers mike
