Could you post the console output URL? Thanks [~stack]

> Looking at recent builds of 1.2, I see a few of the runs finishing with kills 
> and notice that a JVM exited without reporting back state. Running the 
> hanging test finder, I can see at least that in one case that the balancer 
> tests seem to be outstanding; looking in test output, seems to be still going 
> on.... A few others are reported as hung but they look like they have just 
> started running and are just killed by surefire.
> This issue is about trying to disable a few of the problematics like balancer 
> tests to see if our overall stability improves. If so, I can concentrate on 
> stabilizing these few tests. Else will just undo the experiment and put the 
> tests back on line.
