UTM 9.4 Home Edition - High CPU load

Hello together,

since upgrading my virtual UTM Home Edition system to 9.4 I notice a high CPU load. With 9.3 the CPU load was at an average of 6 %. Now it's near to 100 %.

This is an actual TOP:

Everything seems to run fine, but the ESXi host is under high CPU pressure and my other running VMs are sometimes a bit slow.

Does anyone else have the same experience with UTM 9.4?

Thank you.

    If you have Endpoint installed on any PCs or servers, do yourself a favor and disable the Endpoint Web Control then wait a couple minutes and run ATOP again and see where your httpproxy CPU is sitting. I'm betting it is related to that. It was for me. Since disabling Endpoint Web Control, everything is normal.

    Endpoint Protection -> Web Control -> Global and disable.

    After updating to 9.401-11 the CPU load was still near to 100%. Now, after deactivating Endpoint Web Control the CPU load decreased to normal state. Thank you for your help. What's going wrong in UTM 9.4 with the Endpoint Web Control?
    But now my endpoints don't have Web Control when they're out of my protected network [:(]. Does Sophos know about this issue?

  • Yeah, unfortunately updating to 9.401-11 didn't help. As to whether Sophos knows of this issue, if they monitor these forums they do. But I haven't opened a support request with them since I'm running the Home version.

    You should know that if you eventually plan to upgrade to Sophos XG Home, you will no longer have the endpoint protection included with the UTM. If you want to retain Sophos for Endpoint, you'll have to purchase their Cloud Endpoint product.
