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.
