Clear Memory without rebooting in Sophos XG

Hi Community,

Is there a way to clear memory (RAM) without rebooting in Sophos XG firewall? its firmware is SFOS 18.0.5 MR-5-Build586.

Memory went up to 90% last week. We rebooted the Sophos XG firewall. Then, Memory came back to around 30%. Now it has been running since 5 days. Now Memory has gone up to 75%.

Is there a way to clear memory (RAM) without rebooting in CLI mode? otherwise we will have to reboot again.

Thanks

  • Hi,
    You should check where the memory went.
    Which device do you use? How much memory the device have?

  • Hi,

    ram usage is only an issue if if is affecting performance and the system is swapping very heavily, otherwise as others have advised it is not an issue.
