Robbie Gemmell commented on QPID-2693:
--------------------------------------
I was never able to explain the issue you saw with needing to restart the
broker, as the only thing that I know of which could definitely have had that
affect was fixed long before I had you try retesting the issue at various
points. I cant think offhand of any changes since that could/should affect that
and have never seen it happen.
The reason the producer would see an effect is that it is the producer
connection's threads attempting to deliver the message straight-through to the
consumer which runs into the full protocol command buffer of the consumer
connection and encounters the issue. As we continue integrating the 0-10 code
path better with the 0-8/0-9/0-9-1 support we will hopefully resolve that.
