Re: 4.0 Consumer OutOfMemoryError bug?
Only the consumer JVM (JDK 1.5) runs out of memory. I am using the default JVM heap sizes which I think is 64MB.
But I put some logging statements in the consumer code to display memory statistics after receiving every message (using Runtime.maxMemory(), Runtime.totalMemory() and Runtime.freeMemory()). I see that max memory is 64MB and the total memory used slowly creeps up to that max mark and then encounters the OutOfMemoryError.
Also I am using a non-durable subscriber, and am using subscriber.receive () with timeout to pull the messages from the Topic (NOT using MessageListener interface). Also the TopicSessions used are non-transacted with Session.AUTO_ACKNOWLEDGE mode.
Hope this helps.
