You're right. This is VERY serious. I've tested it on NT machines with SP2
and most hotfixes installed.
It's even worse: the NT machine reboots so it should come up again, but
when it does, all memory (physical and virtual) is consumed.
(from the previous memory dump ?)
Only a proper shutdown and restart fixes this.
I think this is a seperate bug, but nevertheless again: OH NO !
