Hmm.... I was not aware that it functioned like that. Our current code abstracts away and hides the AMQ interfaces so that they're essentially fire and forget. I'll play around with pulling the AMQ session out to the level of our database transactions and see if that solves our issues. If that is the case, a simple unit of work pattern should be all that we need!
