[jira] [Commented] (ARTEMIS-2892) Replication stopped working after many failovers

["Sebastian Lövdahl (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ARTEMIS-2892?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17225888#comment-17225888 ] 

Sebastian Lövdahl commented on ARTEMIS-2892:
--------------------------------------------

We just saw this in production as well. We're running 2.10.1 at the moment. I don't know much about the internals here, but is there any chance that https://issues.apache.org/jira/browse/ARTEMIS-2868 that was fixed in 2.15.0 could have solved this?

> We have 2 servers that we have been testing the failover capabilities with. We have encountered a situation where replication has completely stopped, but the master is working properly otherwise.
