High memory usage - XG 135 SFOS 19.5.3

Hi Alves I,

Thank you for reaching out to Sophos Community.

Kindly check the following KB for reference and similar post

• Sophos Firewall: Check the CPU usage using the command top
• Sophos Firewall: IPS configuration to prevent high CPU usage
•  Sophos XG 125 Huge memory Usage 

You may also run the following in the Advance shell by going to CLI 

Check the disk usage: df -ha

Check physical and virtual (swap) memory usage: free -m 

Also, would you be able to share your case ID so that we can monitor it further? If there’s none, I would recommend creating one

Can you let me know if you are doing Web Filter in DPI Mode, are not doing HTTPS Decryption, and your web policy includes Warn.

If so, can you switch the policy away from Warn and see if it resolves the growing memory?  If so, this will be resolved in 20.0 MR1.
