Reason for failure (if possible)

From my conversation with @kannon92 :

• this test is only failing on Fedora OS; it does not fail on Ubuntu or Containerd
• this could be a kernel or OS issue we are running into
• kubernetes-ci-logs artifacts: https://gcsweb.k8s.io/gcs/kubernetes-ci-logs/logs/ci-kubernetes-node-kubelet-serial-containerd/1968708022570061824/artifacts/

Anything else we need to know?

Me and RedHat folks are looking into this!
