Has anyone seen this error? Error response from daemon: cannot stop container: storagenode

Error response from daemon: cannot stop container: storagenode: Cannot kill container b4315dd28c46a4c796607ebc5fffb7e1e485a305f9176ac59d19ba6f21ddeb59: unknown error after kill: docker-runc did not terminate sucessfully: container_linux.go:393: signaling init process caused "permission denied"
