Error description

• You are running CICS Transaction server 4.2 and recently
  applied RSU 1312, You receive the following error over and over:
   DFHAP0001 An abend (code 0C4/AKEA) has occurred at
                      offset X'058E'   in module DFHICUS.
  A dump at the time of the program check showed task CSSY
  running. It is processing an ICE control block, retrieving the
  field ICE_ICUS_PTR at offset x'20'. This should be a pointer to
  a security extension, but instead is zeros, causing the program
  checks.
  
  When this ICE was built, it was assigned REQID that was already
  in use, causing a DUPLICATE_NAME exception.  Code added
  by  PM79818/UK93348 freemained this ICE_ICUS_PTR, but still
  reused the ICE after assigning a new REQID.  Here are some
  trace entries showing this being built:

  ****************************************************************
  A path exists within DFHICP where an ICE Security Extension is
  Freemained after DFHICP attempts a Temporary Storage PUT as
  part of ICE processing but the TS PUT failed because the TSQ
  was already in use. As a consequence, ICE field ICE_ICUS_PTR
  was zeroed.  Subsequent to this, DFHICUS attempted to reference
  the ICE Security Extension via ICE_ICUS_PTR but as it contained
  zeroes it abended 0C4 as it tried to update low core storage.
                                                                 .
  In the case of a TS PUT failure due to a duplicate TSQ name
  being used, DFHICP should not FREEMAIN the ICE Security
  Extension but attempt a TS PUT to a different TSQ.
                                                                 .

Problem conclusion

• UK93348 UI12855
  DFHICP has been modified to not Freemain the ICE Security
  Extension in the aforementioned scenario.
