ORA-06500: PL/SQL: storage error
 *Cause: PL/SQL was unable to allocate additional storage.  This message
         normally appears with an ORA-4030 or ORA-4031 error which gives
         additional information.  Sometimes this error can be caused by
         runaway programs.
 *Action: 1) Ensure there are no issues or bugs in your PL/SQL program which
             are causing excessive amounts of memory to be used.
          2) Programmatically cause unused objects to be freed (e.g. by
             setting them to NULL).
          3) Increase the amount of shared or process memory (as appropriate)
             available to you.
