[rabbitmq-discuss] flow control blocked producers vs consumers

Thu Aug 1 18:42:36 BST 2013

Are you sharing one connection between producers and consumers? You would 
need a separate connection (not just a different channel) for consumers in 
order for them to continue working when flow control blocks the producer's 
connection. Because if you are sharing one connection, blocking the 
producer's connection would also block consumers using that connection, I 
believe.
