james strachan updated AMQ-850:
-------------------------------
Summary: add the ability to timeout a consumer to prevent a bad, hung
or unused consumer consumer from grabbing messages (was: add the ability to
timeout a prefetch buffer to prevent a single consumer grabbing messages)
Description:
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
