> I've found that if I configure Jencks with a low maxMessagesPerSessions (e.g. 3) and a higher maxSessions (e.g. 8) then my consumers hang after about 30 messages and no more messages get consumed.
> Any idea why this might be? I find that if I make the maxMessagesPerSessions (which AFAIK matches the queue prefetch value) higher then it seems to work. I'm happy to do this, but I'm puzzled as to why this occurs.
> Any help gratefully accepted - sample Spring config below. Also, I've attached sample code to this issue. Run the RequestHandler server from within Eclipse against a standalone broker, and then just use the ActiveMQ Web Console to sent 1000 messages to the queue RA.request
