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

[Joel Fritz <JFritz@xxxxxxxxxxxxxxxx>]

Well...almost never.  Shortly after we upgraded to v3r7 I was testing a
program.  It had an infinite loop.  I was unable to end it with sysrequest 2
or endjobabn because, according to IBM, it had somehow flipped a low level
flag that allowed it to shut out all other processes.  Their theory was that
it would have happily excluded other processes as long as the machine had
power.  They sent us a PTF very quickly.  Wish I knew what happened in
greater detail.
