Local fix

Problem summary

  • In a PowerHA or SAMP cluster, in rare cases when RMC becomes
    blocked in certain critical thread paths, multiple exit
    notifications could be received which result in a core dump.
    A loss of this subsystem will bring down an active cluster node.
    

Problem conclusion

  • Redundant exit notifications will now be more appropriately
    handled.
