Description Jessica Forrester 2020-04-20 15:28:59 UTC 
On a 4.4.0.rc8 cluster, after 72 hours post-install the kubelet on master-0 stopped reporting back. Resulting in the node reporting NodeStatusUnknown and the node going NotReady. Nothing was happening on this cluster over the weekend, and very little had been touched on it from an OOTB AWS installation. I believe the only changes were to configure an alert manager receiver.
