Error description

• A batch job was accessing queues that are protected by an
  Advanced Message Security (AMS) policy.  The job was cancelled.
  
  Then, a batch job was run to clear messages from these queues.
  
  The CSQUTIL EMPTY job failed with:
    CSQ0214E CSQ0COPN Message protection initialization failed,
    return code 12, reason 00000000
    CSQ0217E CSQ0COPN Failed to process object 'not available'
  
    CSQU083E  MQOPEN failed for queue <queue-name>.
    MQCC=2 MQRC=2217 (MQRC_CONNECTION_NOT_AUTHORIZED)
  
  In the same second, the AMS job failed with:
    IEF450I CSQ2AMSM CSQ2AMSM - ABEND=S422 U0000 REASON=000001A0
  
  The associated queue manager then failed with:
    *CSQV086E QUEUE MANAGER ABNORMAL TERMINATION REASON=00F00003
  
  
  422
  Explanation:
  This abend is a general use abend code. It provides an abend
  that will be treated similarly to a 222 abend generated by a
  CANCEL. This abend will not be delivered to the target task if
  the task is already in recovery processing.
  
  xxxx01A0
  This abend is the result of the kernel terminating a thread.
  The thread and its associated task are terminated.
  
  
  The initial problem occurs after the application is cancelled
  while an AMS request is being processed by the AMSM address
  space. Recovery processing for the application TCB marks the
  Q0RF control block as orphaned, indicating that the AMS
  service task processing the request should clean up resources
  in AMSM address space relating to the request.
  
  When the orphaned request is processed, the task detects that
  one or more temporary buffers were allocated for the request
  and attempts to free them. However an error in CSQ0DPCS causes
  an invalid address to be freed - this results in an abend 978.
  Recovery handles this abend but reattempts the cleanup,
  resulting in a secondary 978 abend, which causes the AMSM
  address space to terminate, bringing the queue manager down
  with it.

  * PROBLEM DESCRIPTION: Abnormal queue manager termination S6C6 *
  *                      with REASON=00F00003 occurs following   *
  *                      the abend/termination of an application *
  *                      using AMS protected queues.             *
  ****************************************************************
  An application thread calling an AMS function as part of an MQI
  request involving a protected queue had allocated one or more
  temporary buffers to hold parameters, and was canceled while
  waiting for the AMS request function to complete.
  The request area associated with the request was flagged as
  orphaned to indicate that it wouldn't be cleaned up by the
  application task, and should be cleaned up by an AMS worker
  task instead.
  When the worker task attempted to free the temporary buffer(s)
  it abended S422 due to an error, resulting in the AMSM address
  space terminating.
  This was detected by CSQ0DEAD, causing the queue manager to
  terminate abnormally as well.
  

Problem conclusion

• The processing of orphaned application request areas has been
  corrected to prevent the S422 abend.
