Rob Godfrey commented on QPID-6482:
-----------------------------------
OK - the "interesting" thing here is the "Unknown endpoint Transfer".
Basically this is saying that the message has been received on a link, but the
client doesn't know what that link is... The NullPointerException happens
because of a bug in the client where you have a large message which has
encountered the above problem.
Is it possible to turn the protocol logging on and get a bit more context for
the flow of frames/messages from the broker to the client. We need to
understand how the client (or broker) has got into a state where it is
receiving messages.
Do the broker logs show any exceptions?
