****************************************************************
* PROBLEM DESCRIPTION: DBRC API does not free the DSPESTAE     *
*                      storage after DBRC API STOPDBRC         *
*                      command gets called.                    *
****************************************************************

****************************************************************
DBRC API does not free the DSPESTAE storage and every STARTDBRC
command is being executed will allocate new DSPESTAE storage
block. This leads to a memory leakage.

As for the solution to this problem, we need to free the
DSPESTAE storage when STOPDBRC command gets called.

    



Problem conclusion
