Subject: Re: [drlvm][classloader] classloader.StressLoader hangs on my 2-cpu
 Linux box. Does anyone else see this problem?

Has there been progress on this issue?

My CC setup is hung running classloader.StressLoader in interpreter  
(on a 2-cpu RHEL4 box).  It actually has been hung for weeks now, but  
I only just noticed it.
