OpenShift pod to pod internal network connectivity failing.

Solution Verified - Updated -

Issue

  • Connections are being dropped when pods are trying to communicate to each other.
  • I am seeing intermittent network connectivity between pods in the same project.
  • Error: atomic-openshift-node[ multitenant.go:156] refcounting error on vnid 7666890
  • Pods are restarting due to failed http health checks.
  • Scaling multiple pods up in a project causes issues with pods being able to communicate.
  • After scaling down a DeploymentConfig the communication between pods was lost and any attempt to reach the affected service or the pods failed with a timeout.

Environment

  • OpenShift Container Platform 3.5
