Subject Re: Redelivery behaviour
Date Tue, 18 Sep 2007 09:32:51 GMT

Ok. As far as I can tell redelivery only takes place locally. Once you've
taken a message another worker will not see it even if you call rollback.
The message only goes back to the queue when the worker that took the
message disconnects.

Is there another way to force the message to go back to the queue if you
can't process it?
