APAR status

• Closed as program error.

Error description

• The following abend occurred:
  
  ABN=0C4-00000010,U=XXXXXX  ,C=MQ900.932.CMC
  -CSQMCLMT,M=CSQGFRCV,LOC=CSQMCGLM.CSQMCLMT+offset
  
  The abend occurred during local memory termination for RRSBATCH
  JOB. Local memory termination processing switches to each
  context ACE/EB to do deallocation processing. Before the switch
  it traces the new EB address which is obtained from the ACE.
  Unfortunately the code to trace the EB address uses the
  incorrect ACE address which resulted in the 0C4 abend.
  
  This problem was introduced by new code in V925, so also
  applies to V930 LTS. This problem can also occur during normal
  disconnect processing for RRSBATCH address spaces.

  * PROBLEM DESCRIPTION: An S0C4-00000010 abend is seen during   *
  *                      local memory termination for an         *
  *                      RRSBATCH application.                   *
  ****************************************************************
  During local memory termination for an RRSBATCH application, if
  QMGR trace is turned on then the abend will occur. This is
  caused by a trace entry attempting to dereference the wrong EB.
  

Problem conclusion

• The code has been changed so the trace entry dereferences the
  correct EB.
