Sophos XG 125 Huge memory Usage

Hello, I have a sophos XG 125 with last release 18.5.1 configured in HA (active-standby). The memory consumption is always between 85%-92% even after a restart without traffic and load. Yesterday it rebooted after reached 100% of swap usage. I started to encounter this issue of memory usage after the migration from release 17 to 18 few months ago. With release 17 memory has never gone more than 85%.

Below, some images with my situation. Snort is consuming the RAM.

Can someone help me to troubleshoot the issue?

Thank you,

Alessandro

  • I guess this is Webadmin, Userportal etc. - Web services on the XG.

    snort processes are again using much memory. Is this screenshot after you restarted IPS?

    Looks like much to much reserved RAM is used by them. They consume 1.2GB Our SNORT processes use 750MB after days of work.
