I was never able to reproduce the hang on a test machine, it only 
happened in production under load.  My boss would kill me if I ran a 
beta jvm in production.

I also haven't seen the bug for a couple of weeks since I limited the 
work done by that jvm in order to avoid the bug.  And I'm not going to 
risk freezing our system in order to hit the bug again.


If I did attach to the jvm with jdb, what good would it do?  What would 
I see that the SIGQUIT thread dump wouldn't show?
