These cases are related to enforcing that some queues run full resp. the HWM is exceeded. Sorry I cannot be more precise at the moment; I tried to reproduce the behavioural differences with some reduced code example, but have not been successful so far. To enable me to facilitate a more focused reproduction of the issue, I have a general question in advance. Have there been any deliberate changes in behaviour between 4.1.5 and 4.2.1 that might be related to this? From reading the release notes, I did not find something that raised my attention.

One major change is that setting HWM works also after
connecting/binding, is that what you are doing?

There were many other bug fixes that can be seen in the git log, can't
remember all of them off the top of my head

Also what transport mode are you using?

Kind regards,
