On revision 581885 I turned on debug messages on Usage.java and the commented lines of System.out on Message.java and I see the memory usage increase beyond 100% to something like 16500%. This causes a problem for the next thing that calls Usage.waitForSpace(timeout) and causes an indefinite hang
The Usage.increaseUsage(value) does not check to see if it's full and so can keep allocating even beyond 100%. This seems to be happening a lot from Message.incrementReferenceCount() with no corresponding Message.decrementReferenceCount() happening. In my case it happens when a publishing to a topic (~ 1000 msgs) with a offline durable subscribe with multiple hard disconnects from the subscriber. -- View this message in context: http://www.nabble.com/Usage-Manager-for-durable-offline-subscriber-tf4572289s2354.html#a13051280 Sent from the ActiveMQ - Dev mailing list archive at Nabble.com.
