IT13046: SERVER CAN DEADLOCK IN ADMSERVERMONITORTHREAD

Subscribe

You can track all active APARs for this component.

APAR status

  • Closed as program error.

Error description

  • Server can enter a deadlock state and become unresponsive to
    new storage request due to an AdmServerMonitorThread holding to
    many locks for longer than a necessary amount of time.  The
    problem has been seen mostly when AdmServerMonitorThread is
    processing at the same time Replication and or Protect Stgpool
    operations are processing.
    

Local fix

  • AdmServerMonitorThread starts shortly after the server is
    started and runs every 24hrs after that time.   Run time will
    vary depending on the amount of storage defined to the server.
    The problem can be avoided by not allowing Replication or
    Protect Stgpool operations during the time period that
    AdmServerMonitorThread is running.
