Solution Verified - Updated -

Issue

  • OpenShift-SDN is triggering the below alerts:

    NodeProxyApplySlow (openshift-sdn): Configuration of proxy rules for Kubernetes services in the node is taking too long and stale endpoints may exist.
NodeProxyApplyStale (openshift-sdn): Stale proxy rules for Kubernetes services may increase the time to configure the network and may degrade the network.

  • Due to the aforementioned alerts, some of the PODs and deployments are getting delayed.
