An upstream load-balancer monitoring and directing traffic to a group of standalone VIPRION chassis may not stop sending traffic to a particular VIPRION system after this suffers an internal interface failure. As a result, some application traffic may fail. For more information, refer to the bugtracker link in the Symptoms section.
