Subject Re: ActiveMQ Spring listener suddently stops working
Date Thu, 12 Mar 2015 15:36:54 GMT
How many messages get processed before it stops working?

I see it's using CLIENT_ACKNOWLEDGE; have you confirmed that the ack
happens on all code paths (including exceptions)?  It's been a while, but I
think what happens if you don't ack messages is that you can only process
your prefetch buffer worth, so once you fail to make that number of acks,
you're done.
