    I have unsolved open ticket for the high memory usage our device memory usage has been around 90% (+-10%) since end of the last year.  This created was 29.11.21 but issue started month earlier.

    After multiple calls/emails our ticket was finally escalated and I got this reply yesterday (02/03/22) from Sophos support.  The issue is Exim service which is for sending emails is utilizing high CPU. Our unit is XG210 with 30 users.

    Support solution

    • The top output does not cover the system services CPU usage, it covers the CPU usage for user-space services.
    • The CPU graph in diagnostics > system graph also does not cover the system services usage, it covers user space services.
    • The control CPU percentage show for system and user services, so it is high

    Next Actions:

    • Is there any impact due to the high CPU shown in the Control Center?
    • If there is no impact then there is no need to do anything. 
    • If there is a impact due to the high CPU shown in the Control Center then we can try a workaround which required downtime of 15-20 minutes and restart of SMTPD services. 

    To be honest I don't think anyone want to see their firewall resource monitor hovering near %100 and clow red hot, so defenetly want it to be fixed.

    Hope this helps if you're struggling with the same issue.
