OpenShift xtables lock errors.

Solution In Progress - Updated -

Issue

  • Having network problems, when running iptables commands xtables lock errors are seen.
  • Builds are failing with the below error:
atomic-openshift-node[10569] kubelet_pods.go:1121] Failed killing the pod "myapp-deploy": failed to "KillPodSandbox" for "xxxx" with KillPodSandboxError: "rpc error: code = Unknown desc = NetworkPlugin cni failed to teardown pod \"myapp-deploy\" network: CNI request failed with status 400: 'Failed to execute iptables-restore: exit status 4 (Another app is currently holding the xtables lock. Perhaps you want to use the -w option?\n)\n'"
  • After idling my deployments in OpenShift xtables lock errors are seen and service fail with "no route to host"
