Why SQL Server docker image uses high CPU all the time, and how to fix it?

Using this docker-compose.yml I have created a container:

version: "3.9"
services:
    database:
        image: mcr.microsoft.com/mssql/server
        user: root
        restart: always
        container_name: ContainerNameHere
        volumes:
            - /Organization/Databases:/var/opt/mssql/data
        environment:
            - ACCEPT_EULA=Y
            - SA_PASSWORD=password_here
            - MSSQL_PID=Express
        ports:
            - 1433:1433
        logging:
            driver: none
        networks:
            - NetworkNameHere
networks:
    NetworkNameHere:
        name: NetworkNameHere
        driver: bridge

And it has **ZERO** user databases in it. It's just a simple empty SQL Server docker container with no database and no data in it. But here's my top command's results: As you can see, it's totally destroying my VPS. This is so frustrating and the Microsoft team has not [answered me](https://github.com/microsoft/mssql-docker/issues/644#issuecomment-943567909) yet. Why SQL Server's docker container acts this way and what should I do to fix this? --- I have 10 GB of free space: df -h / > Filesystem Size Used Avail Use% Mounted on /dev/sda1 20G 8.9G 10G 47% / My SQL Server build version is 15.0.4153.1, which means it's SQL Server 2019 CU13. My host OS (that runs the docker demon) is Debian GNU/Linux 10 (buster).
