Hey Guozhang Thanks for the reply, No nothing at all in the logs to suggest anything went wrong.
Its really puzzling as to what's happened. When I restarted the consumer everything worked again. Prior to the restart I even stopped the producer for a bit. However any messages that got assigned to the Broker C never got processed. When I ran the console consumer script before I restarted it was able to all print all messages, including messages on broker C. It seems to be that for my consumers consumergroup one of the brokers messages just became inaccessible.
