FULL PRODUCT VERSION :
java version "1.6.0_01"
Java(TM) SE Runtime Environment (build 1.6.0_01-b06)
Java HotSpot(TM) Client VM (build 1.6.0_01-b06, mixed mode, sharing)

FULL OS VERSION :
Microsoft Windows 2000 [Version 5.00.2195]

A DESCRIPTION OF THE PROBLEM :
The VM crashed while running JBoss server. The machine in question was being prepared for production, hence it had little or no traffic load on the server at the time of the crash. I was running the JBoss server at the time. It was a new installation and none of my own web applications were deployed. As far as I can tell, the crash occurred while JBoss was simply idle.

Also, my machine crashed with a "blue screen of death" shortly afterward.

I suspect that the machine may be somehow unstable, as I had problems with
it locking up a couple of times since this happened.

The server had been running for approximately 20 hours at the time of the crash.


THE PROBLEM WAS REPRODUCIBLE WITH -Xint FLAG: Did not try

THE PROBLEM WAS REPRODUCIBLE WITH -server FLAG: Yes

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
The problem only happened once, I have not tried to reproduce.
