jbertram opened a new pull request #2901: ARTEMIS-2421 periodic journal lock evaluation
URL: https://github.com/apache/activemq-artemis/pull/2901
 
 
   If a broker loses its file lock on the journal and doesn't notice (e.g.
   network connection failure to an NFS mount) then it can continue to run
   after its backup activates resulting in split-brain.
   
   This commit implements periodic journal lock evaluation so that if a live
   server loses its lock it will automatically restart itself.
