I'm suprised you can even measure the cpu utilization of a single synchronization unless you're deliberately stressing it and it is doing a lot of "spin locking" View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4174559#4174559 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4174559

The jbossas part of jboss-head (though originallly not intended for that purpose) is meant now to be the place where you integrate thirdparty components so you can see what their individual dependencies are instead of a build ball of mud like varia. For more of my opinion of varia, see the "VARIA MUST DIE" thread in the MC forum. ;-) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4174557#4174557 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4174557

I haven't seen this test fail before, so you need to validate that you haven't introduced a point of contention with your fix. I doubt this new transient failure is a conincidence. e.g. Run this test (and maybe some of the other stress tests) with more load for a longer time with both the old and new code and see hoiw long it takes.

The issue should be transient as the testcases are passing on my laptop. It looks like #881 had problems with load on the machine as BasicTimerUnitTestCase also had a timeout problem. IMHO - we need a dedicated machine (non-VM) to run the testsuite - otherwise the *StressTestCase suites will fail randomly. I'll create a new issue if the problem persist or re-open JBAS-5095 if some of the parameters should be changed.
