liggitt, not sure of root cause. src/k8s.io/kubernetes/pkg/kubelet/dockertools/manager.go: return kubecontainer.ContainerID{}, fmt.Errorf("failed to apply oom-score-adj to container %q- %v", err, containerInfo.Name)
I have run [TEST] for PR 8334 many times. The tests end in failure in different places. I am not sure what is going on.
