Symptome
Extreme memory utilization per node within control plane nodes is extremely high, and could impact responsiveness and stability.
Ursache
The memory utilization per instance within control plane nodes influence the stability, and responsiveness of the cluster.
This can lead to cluster instability and slow responses from kube-apiserver or failing requests specially on etcd.
Moreover, OOM kill is expected which negatively influences the pod scheduling. If this happens on container level, the descheduler will not be able to detect it, as it works on the pod level.

Lösung
To fix this, increase memory of the affected node of control plane nodes.
