Docker container non-deterministic fail

I am trying to start a container with the following command:
`docker run --rm -it --net=host cal_compass:latest`

Sometimes it starts right up. Other times it gives me this error: `Cannot start container 05621665b072b85b6419f904c0ffb511a1ad07a32c1ca675820aaadbefa4a316: [8] System error: write /sys/fs/cgroup/cpuset/system.slice/cpuset.cpus: invalid argument"`

Any ideas what could be wrong? Thank you for any insights

So it turns out that the post-running script for docker service relies on the image "hello-world:latest"

I had uninstalled that image to save space. 

Redownloading image and trying again

This appears to have fixed the issue
