[ https://issues.apache.org/activemq/browse/AMQ-850?page=comments#action_36741 ] Vadim Pesochinskiy commented on AMQ-850: ----------------------------------------
Even with prefetchSize=1 you will already loose 1 message. Somehow people tend to assume that loosing 1 message is not a big deal :-). In many cases it is a big deal, because there is a client can be waiting for response. Thinking about this problem as a performance issue seems wrong to me. I think of it more like a graceful recovery from crash/bug/hang. > add the ability to timeout a consumer to prevent a bad, hung or unused > consumer consumer from grabbing messages > --------------------------------------------------------------------------------------------------------------- > > Key: AMQ-850 > URL: https://issues.apache.org/activemq/browse/AMQ-850 > Project: ActiveMQ > Issue Type: New Feature > Components: Broker > Reporter: james strachan > Fix For: 4.2 > > > If a MessageConsumer is created but not used, it still tends to get its > prefetch-buffer worth of messages.
