Subject Nework of brokers and Topic leak memory
Date Tue, 07 Oct 2008 21:04:09 GMT

We  use a network of brokers and topic to do messaging. All our message
producers and consumers talk to the local VM broker. We reply on bridges
between network of brokers to move messages between brokers. 

I attached two files to show this memory leak problem. TryJmsClient keeps
sending persistent messages to a Topic. TryJmsManager has a message
consumer. Start TryJmsManager first and then start TryJmsClient. After
running about 10 seconds, TryJmsClient stops sending because of getting
"SystemUsage memory limit reached" error. About 24K messages are sent and
consumer shows it get all messages. Now examine ActiveMQ MemoryUsage
printout of TryJmsClient, MemoryUsage percentage stays at 100% or 99%
forever. Producer can never send any more messages.

Note1: If I slow down sending by adding a sleep, I don't see memory leak
immediately. I am not sure for longer running time.
Note2: If I use Queue instead of Topic, there is no memory leak.
