PH62180: LOOP WITH MESSAGE DFHDS0002 CODE X'0071' IN MODULE DFHDSSR

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• A FOR region did not respond and was issuing a lot of DFHDS0002
  messages and it must be cancelled in  order to bypass the
  problem. CICS log shows these messages appear continuously:
  DFHDS0002 ARGCIPFA A severe error (code X'0071') has occurred in
                     module DFHDSSR.
  DFHME0116 ARGCIPFA  416
    (Module:DFHMEME) CICS symptom string for message DFHDS0002 is
         PIDS/5655Y0400 LVLS/710 MS/DFHDS0002 RIDS/DFHDSSR
         PTFS/UI62864 PRCS/00000071
  ...
  The internal trace shows a transaction CSMI in a loop with these
  trace entries (and sending then the DFHDS0002 and DFHME0116
  messages):
  .
  DS 0005 DSSR  EXIT - FUNCTION(RESUME) RESPONSE(INVALID)
  REASON(INVALID_SUSPEND_TOKEN)
  .
  DS 0004 DSSR  ENTRY - FUNCTION(RESUME) SUSPEND_TOKEN(0000011C)
  .
  DS 0071 DSSR  *EXC* - RESUME_INVALID_SUSP_TOK - FUNCTION(RESUME)
  SUSPEND_TOKEN(0000011C)
  .

  * PROBLEM DESCRIPTION: Message "DFHDS0002 A severe error       *
  *                      (code X'0071') has occurred in module   *
  *                      DFHDSSR" is issued repeatedly.          *
  ****************************************************************
  During the run of CICS, message "DFHDS0002 A severe error
  (code X'0071') has occurred in module DFHDSSR" is issued
  repeatedly. CICS Trace will show that a dispatcher resume
  request is failing with RESUME_INVALID_SUSP_TOK and this will
  also be looping.
  

Problem conclusion

• DFHL2DS has been altered to ensure that resume requests that
  respond with a RESUME_INVALID_SUSP_TOK are handled appropriately
  and the corresponding response is returned to the caller.
