Re: is operating system always to blame, was: Ready to scrap an AS/400

That's what makes it an AS/400! It may run VERY SLOWLY, but never an orange
light or a hard lockup. Those days were gone (I thought) with V3.x and
certainly with V4.x. I do wonder, when someone says their 400 locked up, if
it wasn't still slowly churning thru the code. Even a runaway pgm is still
running. Sometimes it is faster to IPL, but not necessarily required. Hard
lockup is still a bug.
Never Reboot!
