Error description

• You are running CICS Transaction server 5.1
  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:

  DFHTS0001  AN ABEND (CODE 0C4/AKEA) HAS OCCURRED AT
             OFFSET X'3A1E' IN MODULE DFHTSPT.
  DFHTSPT is trying to move the security extension, but
  the address passed to it by DFHICP was zeros...
  This type of ICE - x'40' - ICEINT, should have a
  security extension, which are x'83C' in length.
  Code was able to move from location 00000000 for the first
  x'800' bytes, because it is not fetch protected. When it
  attempted to move the last x'3c' bytes, the program check
  occurred due to the PSA+800 being fetch protected.

  ****************************************************************
  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

• UK95275 UI12856 UI13353
  DFHICP has been modified to not Freemain the ICE Security
  Extension in the aforementioned scenario.
