I have a situation where I am receiving messages from a message queue in a transacted session using local transaction. The idea is that the message isn't acknowledged until I am sure that the message was fully processed...if there was an error processing, I'd like the message to remain on the queue for a future retry.
Occasionally during the handling of the message, a handler will crash or be terminated without a clean shutdown. This seems to leave the messages that were being handled at the time of the crash in a state where they can no longer be dequeued...a queue browser shows that they are still there, but a receiver cannot receive them. Is this the intended behavior? Can you point to any documentation on what is supposed to happen in a transactional message receiver in the case of a connection failure? Is there a way to detect and to "unstick" these message?
Thanks.
