I am experiencing this issue too. Every 3-4 days, I can no longer start any docker containers. I get the following "no space on device" kind of error for each container.
docker: Error response from daemon: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: unable to apply cgroup configuration: mkdir /sys/fs/cgroup/docker/92f1ef37cbe933b33651c450bfb566b2243b365d4bae76b791f7c5f990f5ec67: no space left on device: unknown.
Unlike the posters above me, I am not running the nvidia container and my /run directory is not being filled. I tried the suggestions posted there anyways with no success.
I can't find any directory or drive that is being filled. df -h yields nothing concerning.
A reboot fixes this, but this is extremely annoying.
