Description

If a federated link is established to a source broker that is slow to respond with the AMQP handshake, the destination broker cluster will shutdown with an "Unknown connection" error.

Exception constructed: Unknown connection: Frame[BEbe; channel=0;

{ClusterConnectionDeliverDoOutputBody: limit=2048; }

] control 2.0.0.0:22138-14 (qpid/cluster/Cluster.cpp:542)

Steps to Reproduce:

1. Configure a clustered broker
2. Start netcat in listen mode (nc -l 6000)
3. Add a route between the clustered broker and nc (qpid-route queue add localhost:5672 localhost:6000 amq.fanout foo)
4. Clustered broker shuts down
