    ****************************************************************
    During shutdown processing CSQP9DWS is called to synchronise
    with the deferred write processor tasks. If more than one buffer
    pool is still being flushed when this occurs, an error in how
    CSQP9DWS records the current number of flush requests leads to
    the queue manager hanging.
    

Problem conclusion

  • CSQP9DWS is changed to correctly record the current number of
    flush requests, preventing the hang condition from occurring.
