Error description

  • A WMQ 8.0.0.2 queue manager had to be killed because it did
    not stop normally. Attempts to restart it hang.
    .
    Stackit output shows that all of the queue manager processes
    are idle, except for one thread in amqzxma0, which is in
    this stack:
    .
     aoiGetState()
     aoiCheckpoint()
     aocPerformCheckpoint()
     apiStartup()
     kpiStartup()
     zxcStartupLogic()
     zxcExecutionController()
     main()
    .
    The situation does not resolve after waiting 30+ minutes,
    and restarting the queue manager does not resolve it either.
