The sw-engine process causes high CPU usage on a Plesk server

    Hello, this error caused my CPU to be at 100%, and I cannot log in to the Plesk control panel. Following this method is still ineffective, and even after starting sw-engine, the usage rate is still very high. Can you tell me how to fix it?

    Hello, I have the same issue. Yesterday my VPS gets 100% CPU usage caused by mariadb and sw-engine. I tried the above solution, but when I start sw-engine I got 100% CPU usage again. I tried this couple of times and every time I stopped sw-engine, there was same stuck processes. After a couple of hours (may be 3 or more), the problem gone and CPU usage was back to normal. This morning exactly same issue. And again after 2 and a half hours it's back to normal.

    Please take care of this problem, or tell some workaround. Obviously it's not an isolated case. I can provide logs or  whatever you need. My VPS is:
    8vCPU, 16GB RAM, 400GB SSD, Ubuntu 22.04.3 LTS (GNU/Linux 5.15.0-87-generic x86_64)
