> We've seen consumer timeout ("Error registering consumer: 
> org.apache.qpid.AMQTimeoutException: Server did not respond in a timely 
> fashion"). This was seen with volume testing, and 45,000 messages in the 
> queue the consumer was attempting to connect to.
> The issue there is that for every subscription request it needs to go over 
> the whole queue, to work out which messages should go to which subscriber. 
> The broker runs with number of threads == number of cores, so if you have 
> lots of consumers they will queue up behind one another to get processed. One 
> solution is to stagger the consumer starts on the appication side, but we can 
> also expose the connection timeout for configuration so that applications can 
> use this.
> Thus need to create a configurable timeout for sync responses. Rob Godfrey 
> can advise if further info required.
