>
> When a connection is created, we don't verify in the first step that both the
> source and destination exist. In the case of a Remote Process Group, where
> the ports change in the background, this can become problematic, we one node
> in the cluster may not have the same ports as another and the connection
> creation could end up failing on that node, resulting in the node getting
> kicked out of the cluster. We should also verify that the new destination
> exists when updating a connection if its destination changes, as this could
> happen there as well.
