this quad system constantly has 80% useage on all 4 procs??? is this
normal???

We hit 650 users today and had to reboot.  Not good.  The system was
still
running but the load was so high that it would not move.  There seem to
be atleast
2-3 process left hanging after someone logs out.  usually -sh and our
bussness
application.

What in a program can cause it not to die when your session is over? and
what can i do to help clean these up rather than just haveing greping
them out
of a ps and killing them?
