Juliano Carniel commented on AMQ-1927:
--------------------------------------
Just to give the feedback i've promissed.
I've tried the producerFlowControl turned on, and the lock problem persists. We
have seen one of our systems, at the end of a transaction when it will produce
a message to a queue, it "stay running" and the thread gets the state of
"Waiting", the same as the one reported above.
When i tried this with the producerFlowControle turned off, it worked perfectly.
Thanks.
