The memory allocation for the DSM application should be a minimum of 8 GB. Windows alerts and DSM logging provide warnings and notifications if the allocated memory is too low. To resolve the issue, increase the RAM available to the DSM.

To increase the allocated memory

 
Make the sure the server has enough memory to handle the increased demand for resource.
  • For Windows
    1. Go to the DSM directory. This is the same directory where the Deep Security Manager.exe is located. For example:  C:\Program Files\Trend Micro\Deep Security Manager.
    2. Create a new file named 'Deep Security Manager.vmoptions'.
    3. Edit the file by adding this line, wherein "8g" will make 8 GB of memory available to DSM:

      -Xmx8g

    4. Save the file and restart the DSM.
  • For Linux
    1. Go to the DSM /opt/dsm/.
    2. Create a new file named 'dsm_s.vmoptions'.
    3. Edit the file by adding this line, wherein "8g" will make 8 GB of memory available to the DSM:

      -Xmx8g

    4. Save the file and restart the DSM service using this command:

      service dsm_s restart

To verify the configured memory

  • For DSM 9.0 and above:
    1. On the DSM console, go to the Administration tab and click System Information in the left menu. The System Details screen appears.
    2. In the center pane, expand Manager Node > Memory .
      The Maximum Memory value indicates the configured memory.
  • For DSM 8.0:
    1. On the DSM console, click System > System Information in the left menu.
    2. In the center pane, scroll down to the System Details > Memory section. The Maximum Memory value indicates the allocated memory for the DSM.
