Potential Bug: Openshift does not always clean up all containers within a Pod when the Pod is removed. There were a few instances where one of the containers from the Pod were left running even though the Pod was successfully removed and the other containers within the Pod had been successfully shutdown and removed.
Containers that use UDP (Layer 4) and do not go through the Openshift networking layer can find other containers running in a Pod with a Service defined. Potential impact to mutli-tenant boundaries.
