Docker compose insecure/mariadb/fpm example 'OCI runtime create failed'

I use the docker-compose.yml from the .example/insecure/mariadb/fpm folder.

If i run docker compose up i get the following error.

Attaching to nextcloud-app-1, nextcloud-cron-1, nextcloud-db-1, nextcloud-redis-1, nextcloud-web-1
Error response from daemon: failed to create shim: OCI runtime create failed: container_linux.go:380: starting container process caused: process_linux.go:385: applying cgroup configuration for process caused:

I tried it with user: "1000:1000" for the app container, but same problem.

System is Debian 10.13 with Plesk.

Is that a permission problem in the docker container, or on the host system?

After restarting the server it works.
