We saw a pod, with 44 of these completely break. It's like it just stopped making forward progress. I ran:
oc get --raw /debug/pprof/profile --server=https://172.31.71.195:10250 > profile
and it hung for about a hour. top showed 'openshift' using 100% CPU. I deleted the 'bad' sandboxes, restarted node, and now the node seems largely ok...
# openshift version
