             Summary: LP Bug: 1415187 - MXOSRVR stay around even when trafodion goes down
                 Key: TRAFODION-954
                 URL: https://issues.apache.org/jira/browse/TRAFODION-954
             Project: Apache Trafodion
          Issue Type: Bug
          Components: connectivity-mxosrvr
            Reporter: Guy Groulx
            Assignee: Tharak Capirala
            Priority: Critical
             Fix For: 1.1 (pre-incubation)


Recovery scenario.

Killed off a regionserver.    Recovery kicked-in but for some reason, a watchdog timer poped on a node and the trafodion came down.   IE:   Trafodion shut down.

However, several mxosrvrs stayed up.    Had to explicitly kill them.

    From: Govindarajan, Selvaganes 
    This issue happens due to node down situation.  ESPS, ARKCMP, RMS processes all react to the node down/instance down messages by simply exiting. MXOSRVR also need to do exit without for anything to complete. In case of node down situation, there is no order in which processes can go down.
