[rabbitmq-discuss] Error code 404 NOT_FOUND when declaring a queue in a clustered server (using .NET client)

[Alfonso Pantoja]

Hi Alex,

Sorry, my mistake
You are right. The queues were declared on the offline node.
Due to the way to solve this is to bring back up that node we'll have
decided
that every consumer will point to the server that holds the queues
it needs, so a shutdown on the other node won't affect it .


Thank you


Alfonso Pantoja
