Sorry for the late reply,
@Walter I did try to restore the messages from oldreplica files once, but didn't manage to get the messages back. I think the replica containing the messages was deleted already since too much time has passed since I noticed I am missing the messages. This is all happening on my develop server, so I'm not too concerned about having lost some messages - but I am concerned about implementing artemis in production environment. @Clebert I think split-brain scenario sounds possible. Is split brain a valid scenario in a simple live-backup replicating pair? We are working on writing some tests, however I cannot automate shutting down 2 virtual servers in a java-written test ... and I was never able to replicate this. Vast majority of the time, replication works exactly as expected. Also, can @Walter confirm that you had no problems on version 2.20, since you said you are reverting back to that version? If so, maybe we should check the changes between 2.20 and 2.22. ________________________________ From: Clebert Suconic <clebert.suco...@gmail.com> Sent: 25 October 2022 18:56 To: users@activemq.apache.org Subject: Re: Messages getting lost on Artemis 2.25 To sporočilo izvira izven naše organizacije.
