Short dump after AC_FLUSH_CALL

Question

Hi all,
I'm using Netweaver 04 and I've developed a report that displays a dynpro containing a dynamic document and it auto-refreshes itself through the CL_GUI_TIMER class.
After a period of correct working the report crashes with a short dump about the wrong exit of AC_FLUSH_CALL function module (CL_GUI_CFW->FLUSH method). sy-subrc = 2.
Can you help me? Thanks in advance.

My monitoring application accesses each second a DB table to check if its contents are changed and dispay a particular record on the dynpro.
FILL_HEADER is fixed and FILL_VALUES can change.
This is most of PBO code:
  SET PF-STATUS 'STATUS1100'.
  SET TITLEBAR  'TITLE1100'.
  CLEAR flag.
  IF first = 'X'.     " prima display
    CLEAR:   i_text, is_ma_data.
    REFRESH: i_text, is_ma_data.
    CREATE OBJECT head_cont
       EXPORTING container_name = top_screen.
    CREATE OBJECT values_cont
       EXPORTING container_name = values.
    CREATE OBJECT fill_header
      EXPORTING no_margins = 'X'.
    CREATE OBJECT fill_values
      EXPORTING no_margins = 'X'.
    CALL METHOD fill_header->initialize_document.
    PERFORM fill_field_names.
    CALL METHOD fill_header->merge_document.
    CALL METHOD fill_header->display_document
      EXPORTING
        parent             = head_cont
        container          = 'FILL_HEADER'
        reuse_control      = 'X'
        reuse_registration = 'X'.
    first = ' '.
  ENDIF.
    CALL METHOD fill_values->initialize_document
      EXPORTING
        background_color = bg_color.
    PERFORM fill_field_values.
merge document
    CALL METHOD fill_values->merge_document.
    CALL METHOD fill_values->display_document
      EXPORTING
        parent             = values_cont
        container          = 'FILL_VALUES'
        reuse_control      = 'X'
        reuse_registration = 'X'.
  ENDIF.
refresh
  CREATE OBJECT gui_timer.
  SET HANDLER event_handler->on_finished FOR gui_timer.
  gui_timer->interval = timeout.
  CALL METHOD gui_timer->run.
  CALL METHOD cl_gui_cfw=>update_view.
Thanks.
