> See PROTON-2440 for context.
> The configured keepalive on edge-to-interior connections can fail to provide protection from connection loss. This results in half-failed connections where the edge sees connection failure and re-connects and the interior sees nothing and accumulates multiple connections from the same edge.
> This is a serious problem because the interior will attempt to forward deliveries across these dead-but-seemingly-alive connections resulting in lack of message delivery.
> The solution proposed in this issue is to work around the problem by introducing an application-level keepalive for edge-to-interior connections.
