imho, yes. Isn't the operating system supposed to be in control? And parcel
out resources to various applications? Should it allow any application to
simply take over *all* resources, so that an operator can't even end the
application?

Sounds like a Unix fault to me. Why couldn't it simply stop giving resources
to all applications until something is done about the problem by the
operator/user? Why do you think it good form for the os to simply die?

The hardware isn't the problem, it's the operating system. Fix it. Get it
fixed. If an application can crash the operating system, isn't that as big a
problem as any virus?


These are the kinds of problems that get me very irate at Windoze. When I
switched to NT at home, it was a huge relief to have a task manager that 99%
of the time allows me to zap offending applications. Why can't OS/400 and
Unix do that much?

Don't get me wrong, I think the AS/400 is great hardware and OS/400 is a
really good o/s. The only time I've heard of an application taking over like
that is when someone set their interactive priority to 1. Actually, this
sounds a lot like what Richard Jackson was investigating -- low priority
jobs interfering with higher priority jobs. Can't someone keep a priority 10
job going that can shut down Domino when it locks up the system?
