PK83713: DFHSM0002 STORAGE VIOLATION RECEIVED AFTER TRANSACTION CTIN PROGRAM DFHZCT1 GETS ABEND ATCV

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• You receive a Storage Violation after transaction CTIN and
  program DFHZCT1 suffered an abend ATCV.
  When you suffered the abend ATCV this caused  DFHZCT1's abend
  handler to be driven. This freemained the ctin_parmarea but then
  the task was suspended in DFHZERH processing. At that point a
  CCIN uninstall request was received for the same virtual
  terminal and it also attempted to freemain the same area
  (it is shared between the tasks), and the abend happens.

  DFHSM0002 Storage Violation after both the CTIN and CCIN tasks
  attempt to freemain the same ctin_parmarea. The CTIN install
  task suffers an ATCV abend causing DFHZCT1's abend handler to be
  driven. ZCT1_ABEND freemains the ctin_parmarea before the task
  is suspended in DFHZERH processing. At that point a CCIN
  uninstall request is received for the same virtual terminal and
  also attempts to freemain the ctin_parmarea leading to the
  reported storage violation.

Problem conclusion

• DFHZCT1 has been changed in the abend handler routine ZCT1_ABEND
  so that tcte_ctindata_ptr is cleared after the freemain of
  ctin_parmarea.
