      In prior releases, if a live-backup broker group was configured to use shared store high availability, the live broker might fail to properly activate after a restart, but would continue to hold the journal lock. For example, this issue might occur if the live-backup group was using a network file system (NFS), and the NFS was unexpectedly stopped or removed, causing the live broker to restart. This situation resulted in a a non-functional broker that couldn't service clients but which prevented the backup broker from activating. This issue is now resolved.

    Description

      A pair of master/slave brokers configured to use shared NFS store become <defunct> when the NFS shared store is removed i.e. NFS service is stoped on the machine serving the file system.

      The master broker restarts after the NFS failure in a state where it holds the lock but does not start/deploy the JMS objects and neither does it allow slave broker to get the lock

          • 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.
