Subject [jira] Commented: (AMQ-850) add the ability to timeout a consumer to prevent a bad, hung or unused consumer consumer from grabbing messages

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.

> If a MessageConsumer is created but not used, it still tends to get its prefetch-buffer
worth of messages. If it does not process them within a specific time the consumer should
either be closed, or the messages unacked and flushed from the buffer so that the consumer
does not hog the messages.
> Similarly if a consumer gets a message but then locks up without processing the message
we should lazily kill the consumer releasing and redelivering all its messages
