  This is in label  ESTAE000 - the ESTAE module for this process.
  The program check happens on this instruction:
  .
     4AD6 D70364B064B0  XC    WS_MVS_REASCODE,WS_MVS_REASCODE
  .
  because Reg6 = x'00000000'

Problem summary

• ****************************************************************
  * USERS AFFECTED: All CICS users with UK55327 applied.         *
  ****************************************************************
  * PROBLEM DESCRIPTION: Abend 0C4 happens in DFHXCPRH at        *
  *                      offset +x'4ADC'                         *

  * RECOMMENDATION:                                              *
  ****************************************************************
  DFHXCPRH ESTAE000 tries to clear WS_MVS_REASCODE but R6, the
  base register of working storage, is x'00000000' at that point.
  This causes an S0C4 abend.
  

Problem conclusion

• UK55327
  DFHXCPRH has been changed in ESTAE000 to re-address R6 to point
  at working storage before clearing WS_MVS_REASCODE.
