As your stack trace shows, and as Mark mentions, in your case the x-message-ttl is the parameter that differs.<br><br>I want to take to use the occasion to ask a question in this context:<br>For most of the parameters this is a good approach, but for some parameters this can be a bit annoying, especially for the HA feature, where you specify over which servers a queue is distributed. For the TTL it's a bit similar<br>At least I feel sometimes that it would be good if the queue parameters could be adjusted at runtime, that the mirroring could be changed at runtime, without clients requiring an update.<br>The current approach we have taken is that clients don't define the queues anymore, but they are managed externally. Which is not ideal either :-( If anyone has a good recommendation, ideas, ...
