Set holmes.WithCGroup(true) in the docker container. The log message indicates that the cpu core failed to be obtained.

Should be caused by not adding the resource limit. After starting with the resource limit, it looks OK

docker-compose.yaml

    ...
    deploy:
      resources:
        limits:
          cpus: '2'
          memory: 2g
   ...
