> Consider the following scenario: All the brokers are using a directory
> service based discovery agent (for example, DNS). Broker A comes up and tries
> to connect to broker B, which is not functional yet. The Discovery Network
> Connector at A adds service B to its tracking state "bridges" (list of
> connected services) before activating the connection. However, if there is a
> failure, the data structure is not cleaned up. When the DNS Discovery Agent
> module rescans (DNS) and passes on uri for B into DNC, it simply ignores it
> (as its tracking state hasn't been cleaned up upon prior failure).
> The attached patch should take care of this issue (in the observed code path)
