      A race condition in the JGroups FLUSH protocol caused messages to be processed in the wrong order when the master node left the cluster, so the master node left before sending a new view (with a new master). Therefore, the other nodes did not detect the master's absence, or elect a new master, until the master's absence was detected by the failure detection protocol.
      This was fixed, and the race condition no longer occurs.

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
