Okay, that is what I was afraid of :) Its more like I can process all the messages, it's just one device the message is designated for is busy. I can still process the other 100's of pending requests. So, option #2 is not viable becuase I still need to service the messages I can work on. So I'm thinking #1 is probably where I'd go and I'll either queue the internally & not ack them or put them on another queue back to myself to check on later via a synchronous poll.
Thank you for the repsonse. On the 3rd question though, is there a way to "Move" messages from one queue to another once I've dequeued via async (onMessage)?
