Subject Re: Query on activeMQ Queue's MemoryLimit (consumer getting blocked)
Date Mon, 11 Mar 2013 18:00:07 GMT
If your messages are going to be > the limit, you'll want to revise your
limits. The queue won't keep messages in the cache ready to dispatch once
it reaches the configured limit, but if a single message is larger than
your limit, then it will consume all of the memory.
