Insufficient memory on the Filtering Service machine

The memory required to run web protection software, download the Forcepoint URL Database, and apply Forcepoint URL Database updates varies, depending on the size of the network.

• In a small network, at least 4 GB of memory is recommended (Windows and Linux).
• Refer to the Deployment and Installation Center for complete system recommendations.

When free memory drops below 512 MB on the Filtering Service machine, a health alert message is generated. Buffer and cache space are not included in this calculation.

If the machine meets or exceeds the hardware requirements, and Filtering Service is able to load the Forcepoint URL Database, the low memory condition is unlikely to cause problems.

If Filtering Service is unable to load the Forcepoint URL Database, however, you will need to free up memory on the machine, or add additional RAM.

To check the memory in a Windows system:

1. Open the Task Manager.
2. Select the Performance tab.
3. Check the total Physical Memory available.

You also use the Windows Performance monitor to capture information. To check the memory in a Linux system:

1. Open a terminal session.
2. At the prompt, enter:

   top

3. Compute the total memory available by adding Mem: av and Swap: av.

   To address problems with insufficient memory, you can either upgrade the machine’s RAM or move applications with high memory usage to another machine.
