    Hi David,

     

    Check for traces in "/var/log/messages" file if this node went down due to OOM (Out of Memory) causing this abrupt shutdown.

     

    Also if nothing is found in the messages file please also check dblog (inside the catalog directory and see if something fishy reported out there (like for kernel crash).

     

     

    Thanks

    Rahul
