What does the following message mean?
[LocalPeer ... (broker)] Received connection from [Peer ... (broker)] validation failed, closing connection
This is the way we organize reconnects between brokers:
A broker in the durable membership list ("show domain serverConfig") will periodically reconnect to all brokers in the domain if there's no connection. Any connection request "from right to left in the membership list" is rejected, which is logged as "validation failed, closing connection".
The receiver will transiently store the incoming Broker's advertised address. Then the reconnect
will happen from "left to right" on the membership list.
It is expected to see this message in the agent.log.
