For a few days I've had my Thunderbird Locked on random usage pattern. I ran a debug build and got the following message on the console :

###!!! ERROR: Potential deadlock detected:
=== Cyclical dependency starts at
--- Mutex : nsImapIncomingServer.mLock (currently acquired) calling context
  [stack trace unavailable]

=== Cycle completed at
--- Mutex : nsImapIncomingServer.mLock (currently acquired) calling context
  [stack trace unavailable]

###!!! Deadlock may happen NOW!

###!!! ASSERTION: Potential deadlock detected:
Cyclical dependency starts at
Mutex : nsImapIncomingServer.mLock (currently acquired)

Hmm, I think it's the LoadNextQueuedUrl that's the issue.

anything more I need to provide ?
Severity: major → critical
Component: General → Networking: IMAP
Product: Thunderbird → MailNews Core
QA Contact: general → networking.imap
Summary: Potential deadlock detected → Potential deadlock detected @ nsImapIncomingServer::LoadNextQueuedUrl
On the UI thread, nsImapIncomingServer::LoadNextQueuedUrl calls LoadImapUrl, and eventually  nsImapProtocol::TryToRunUrlLocally notices that we already have the message we were asking for, so it finishes the current url, and eventually the autosync OnStopRunningUrl listener tries to run a new url synchronously, which eventually calls LoadNextQueuedUrl re-entrantly. In the old world, this was OK, but not so much anymore. 

Ludo, I'd be surprised (but happy) if all your hangs are because of this, but I'll try to come up with a patch that breaks the cycle and generate a try server build (can you get symbols w/ those?). When this happens again, attaching a backtrace again would be useful, to see if it's the same issue. When it happened in MV, I don't think that was the stack I saw.

Can they build debug ? I'll be happy to run a debug build :-)
try server builds should be showing up here http://ftp.mozilla.org/pub/mozilla.org/thunderbird/tryserver-builds/bienvenu@nventure.com-c921fb26d3a1
OS: Mac OS X → All
Happilly running with the pacth and no issues so far. Shane Can you give a shot at the try build too ?
Shane was running with the build, w/o a problem, and is going to report back this morning if the stayed working over night.
Attached patch proposed fix — — Splinter Review 
This posts an event to the event queue to send the start and stop running url notifications, so that we don't get re-entrant calls to LoadUrl, in the case that we decide that we don't need to run an imap url to fetch a message because the message has been added to the cache between the time the url was queued up and the time it actually got to run.

While I'm not getting the lockups I had yesterday (yay!) I did still get a lockup on shutdown.  I'm assuming that is not related, since I noticed it once in a while before yesterday.

note on shutdown lockup: seems to happen after laptop sleeps and is awoken.
