We do have producer flow control enabled. However, we were not at that limit. Attached is another stack trace from a linux client. This is on a different
box, but attached to the same broker as the first stack trace I sent (cleaner stack trace). The snip below shows onException. Did something happen that caused a deadlock during a transport failure?

Do you have producer flow control enabled on the broker, that can cause
a producer to block if there's no more space for messages in that
destination.
