APAR status

• Closed as program error.

Error description

• You are running CICS Transaction server 4.2 and receive the
  following messages:
  DFHAP1301 Language Environment has detected a corruption of its
                       control blocks.
  DFHSM0102  A storage violation (code X'0D11') has  been
                        detected by module DFHSMMF.
  DFHAP0001  An abend code (0C4/AKEA) has occurred at
                        offset x'FFFFFFFF' in module xxxxxx.
  DFHDS0002  A severe error (code X'0204') has occurred in module
                       DFHDSTCB
  There was also a KERNDUMP taken.
  Tasks were then stuck in RESUMED EARLY status.
  The tasks abending are running on an L8 tcb, as they are
  defined  concurrency- threadsafe and openapi.
  When the program check occurs, DFHAPLI1 calls DFHMEME  to issue
  message dfhap1301.  DFHMEME calls the dump domain to
  take a dump on the message, and needs lock DUSYSDMP which is
  owned by another task.  When DFHDSSR is called to suspend this
  task, it finds it is in an incorrect state-
  RUNNING_ABTERM_ALLOWED, causing the DS0002 error and the task
  to be stuck in resumed early status.

  ****************************************************************
  A task encounters a program check because of storage violation.
  It calls the LE interface for program_check_recovery, but
  receives return code of 8 indicating that the LE control blocks
  have been overlaid. AP1301 is issued to report this situation,
  and take a dump but the DUSYSDMP lock is held by another task.
  The task fails to suspend because it is in state
  RUNNING_ABTERM_ALLOWED and DS0002 is issued for this failure.

Problem conclusion

• DFHAPLI1 has been changed to switch to correct task state after
  receiving return code 8 from LE for program check recovery.
