PK15593: UNEXPECTED SYSTEM DUMP PRODUCED FOR AZI6 ABEND

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Customer has application running on AOR which issues an EXEC
  CICS READ INTO command against a remote file living on FOR. The
  request is function shipped to the FOR where the mirror task
  fails to be attached due to a security violation (users
  multitask and sometimes cause their userid to be revoked). The
  failure is reported back to the AOR where ABENDAZI6 is processed
  .  The abend is percolated from DFHPCP to DFHISP to DFHFCRF to
  DFHFCDTS. In DFHFCDTS's recovery routine (FCDTSREC), specific
  checks are made for abends AKC3, AKCS and AKC5. If none of these
  then routine EXCEPTION_TRACE is called to record an exception
  trace. Then routine EXCEPTION_MESSAGE is called where message
  DFHFC0001 is issued and a system dump is produced:
    DFHFC0001 CICSAOR1 An abend (code ---/AZI6) has occurred at
    offset X'26F0' in module DFHFCDTS
    Customer does not expect a system dump to be produced for an
  AZI6 abend and feels the abend should be propagated back to the
  application. Much like PQ66717 does for DFHFCRF and DFHFCFR.

  ****************************************************************
  A file control request for a remote CICS-maintained datatable
  fails because of a security violation and an abendAZI6 is
  issued.  Instead of the abend being passed back to the
  application, MSGDFHFC0001 An abend (code ---/AZI6) has occurred
  at offset X'26F0' in module DFHFCDTS and an abendAFCZ are
  issued.  The abend AFCZ occurs because the recovery routine in
  DFHFCDTS returns a DISASTER response for the abendAZI6 instead
  of percolating the abend to the application.

Problem conclusion

• The recovery routines in DFHFCDTS and DFHFCFR, FCDTSREC and
  FCFRREC, have been changed to percolate any abends for shipped
  requests instead of returning a DISASTER response.
  
  A new reason of FCFR_SHIP_ABEND has been added to a number of
  file control commands.
