Error description

• DUMP TITLE=
  CSQ1,ABN=5C6-00F30801,U=BATCH,C=R3600.710.SSSC-CSQAPRHX,
  M=CSQAPRHX,LOC=CSQ3EPX.CSQAPRHX+0000122A
  
   The Batch job was in the middle of MQPUT against a queue
  when a S522 abend occurred. The abend hit when CSQIMPU2 had
  invoked CSQP1RSW to release the latch on the BDSC. CSQP1RSW
  had detected that buffer pool 1 was under stress so had
  issued an execution unit switch to issue message CSQP020I.
  As there was an execution unit switch at the time of the
  abend, the deferred recovery bit, EBDR, was set. This meant
  that the recovery processing in CSQP1RSW did not take place,
  so the latch on the BDSC was not released. This resulted in
  the 5C6-00F30801 abend seen here.

  * PROBLEM DESCRIPTION: If applications connected to a queue    *

  *                      00F3040A.                               *

  ****************************************************************
  The following is a scenario where the problem occurs when there
  is an asynchronous abend of application (i.e. CANCEL) causing
  the reported queue manager termination with REASON=00F30409 or
  00F3040A.
  
  Application putting messages to a local queue with a buffer pool
  that is too small and message CSQP020E is issued at the time
  when the application abends can cause the queue manager to
  terminate.
  

Problem conclusion

• CSQVEUS1 has been updated to introduce a delay to give time to
  active threads to complete avoiding deferred recovery which
  allows the recovery clean up exits to be invoked.
