not sure. or at least, those aren't the symptoms I'm seeing. The
output from the broker is:

I'm not setting a clientId but I'm not using a durable topic either (I
am using an Exclusive consumer, though).

Apologies if this isn't much to go on but I'm at a loss as to what is
happening. Will get source and start debugging soon, though, which
might give me a few more clues.

cheers,
j.
