I suspect it’s either a bug or some weird edge issue.  I’m working on your
theory that the messages are timing out in the client and not being acted
upon but not going into the DLQ.

I can reproduce it pretty easily now.  I have a large batch job that I run
via messages and that immediately chokes and doesn’t forward messages to
the receivers.  I’m just not sure of the best way to debug it at the moment.
