What happened?
    The current program had to be terminated because of an
    error when installing the R/3 System.
    The program had already requested 271435216 bytes from the operating
    system with 'malloc' when the operating system reported after a
    further memory request that there was no more memory space
    available.
Make a note of the actions and input which caused the error.
To resolve the problem, contact your SAP system administrator.
You can use transaction ST22 (ABAP Dump Analysis) to view and administer
termination messages, especially those beyond their normal deletion
date.
Set the system profile parameters
- abap/heap_area_dia
- abap/heap_area_nondia
to a maximum of 271435216. Then reduce the value by 10.000.000 to be on the
safe side.
Then restart the SAP System.
abap/heap_area_nondia and abap/heap_area_dia:
  Set smaller than the memory achieved for each process
  with 'malloc' and smaller than abap/heap_area_total
You should also check whether the available memory (file system
swap and main memory) is sufficient for the started program
and its data.
Error analysis
    When the program was running, it was established that more
    memory was needed than the operating system is able to provide savely.
    To avoid a system crash, you must prevent this
    situation.

Hi,
Try to use open cursor to select the data from db table.
Below is an example for this.
What ever the logic you do this in between DO and ENDDO.
DATA: packsize      TYPE i VALUE 1000,
OPEN CURSOR WITH HOLD db_cursor FOR   "Defect 12319
    SELECT (tab_fields) FROM glpca
    CLIENT SPECIFIED
    BYPASSING BUFFER
    WHERE rldnr IN rldnr.
    DO.
To Fetch data in chunks of 2gb
      FETCH NEXT CURSOR db_cursor
      INTO CORRESPONDING FIELDS OF TABLE i_glpca
      PACKAGE SIZE packsize.
*Begin of defect 12319
      IF sy-subrc NE 0.
        CLOSE CURSOR db_cursor.
        EXIT.
      ENDIF.
  ENDDO.
Or you can also use packaging size option in select statement.
