      Currently we hit around 9100 sessions in the QA lab before running out of heap. It's possible that we can improve on this by cleaning up the sessions more aggressively.

            [WELD-775] Try to reduce runtime use of heap

            Pete, I'm assigning this to you. When you need to verify something, let me know.

            I think this should be the one you're looking for https://hudson.qa.jboss.com/hudson/view/Weld/job/perf-weld-numberguess-load-single-jprofiler/79/artifact/weld-snapshot.jps . It doesn't contain records of method calls, use it in conjunction with the previous snapshot.

            We need to take a heap snapshot at that point as well as the standard JProfiler views so that I can explore the heap and see what is going on.

            The jProfiler snapshot for 1500 sessions is available here: https://hudson.qa.jboss.com/hudson/view/Weld/job/perf-weld-numberguess-load-single-jprofiler/75/artifact/weld-snapshot.jps

            A 1500 snapshot will be good

            You mean JProfiler snapshot? It will not be possible to get it for more than ~1500 sessions. The jProfiler slows all the things down very much so I get sampling errors then. I can only get the curve describing total amount of mem. Or I can get the snapshot for ~1500 at most.

            Martin, could you provide a heap snapshot from the stress test run?
