[rabbitmq-discuss] Envelop redeliver question ( clustering ha redelivery question)

[Vikas]

Hi Emile ,

Thanks for your reply . I've set QoS prefetch count set to one.

The problem is observed in only one scenario 

Node1 and Node2 are running in cluster ha
Stop Node2
Start Node2
Restart Consumer
All old messages are received with redeliver as true .
