Ping operation and physical port collection thread are invoked by vtn coordinator at particular time interval.
When controller goes down ping operation thread will clear the port cache same time physical port collection invoked which leads to Vtn coordinator gets aborted.

Here "Ping operation" means an operation that VTN Coordinator fetches the version of ODL controller from the controller to ensure that the controller is up and running.
