Hi, Firstly thank you and the team for Artemis. We have been using the fruits of your labour from way back in HornetQ days. Thank you.
We have encountered a similar issue to the one described in: https://issues.apache.org/jira/browse/ARTEMIS-2373 I do not have a reproducible test case but I will try to describe what we are seeing. The cluster is symmetric across 24 nodes.The environment is under continual steady load. Sporadically - say once in 10 days we see a node flip into a state where one of the $.artemis.internal.sf.... queues starts to back up. Typically we see pretty much 0 queue depth on these internal queues. The queue continues to fill pushing heap usage to its limit and eventually after an hour OOM. We are running using an Embedded server. We see warnings that the $.artemis.internal.sf... queues do not have Dead Letter or Expiry Addresses configured. Should they be? I realise this is big ask, but what other details can I provide that might help diagnose the issue. Many thanks Graham Stewart
