PM92192: ABENDS S0C4 or STORAGE VIOLATIONS MAY OCCUR WHEN USING CICS HGSC OR HGSU TRANSACTIONS.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• AGGSC (via the CICS HGSC or HGSU transactions) allocates (via
  GETMAIN) some memory intended to be shared among all the tasks,
  but fails to set the bit indicating that the memory should
  shared and outlive the HGSU command task itself.
  
  After the HGSU command task ends, the memory is automatically
  freed, but a globally available pointer to it continues to be
  invalidly used by other tasks, particularly in AGGSC (via the
  CICS HGSC or HGSU transactions) which may abend (typically a
  S0C4).

  * FIX DESCRIPTION:     Memory allocated and used by HGSC/HGSU *
  *                      was expected to outlive the individual *
  *                      HGSC/HGSU transations, but did not     *
  *                      because it was not allocated as SHARED.*
  *                                                             *
  *                      AGGSC code was changed to allocate the *
  *                      memory as shared and free it once the  *
  *                      X option is chosen to exit the program,*
  *                      and end the sequence of transations.   *
