    This APAR supersedes OA42209 and addresses the storage
    overlay problem that causes the agent hang when the agent
    is stopped. New improvements are made on the termination
    processing.
    

Problem conclusion

  • The storage of the communication control blocks between the
    agent and USS threads is changed to be allocated and freed
    by the USS threads. This prevents the storage from being
    freed by the agent while the USS threads are still active.
    
    The following improvements are made on the agent termination
    processing.
    
    1. The enablement of immediate shutdown.
    2. New environmental parameter KQI_SHUTDOWN_WAIT_LIMIT.
