   Here at B-SC we have encountered the infamous ``silo overflow'' from
our dmz. After speaking w/DEC we finally figured out the problem was that
our dmz and the disk are on the same uba controller. The silo will
consistently overflow when screen intensive programs and disk intensive
programs hit the machine during peak loads.
   FYI: we are running ultrix 2.0 on a 750 with a ra81, a tu80, a dmf32
and a dmz32. We only have one uba so short of buying another (and we aren't)
our ``fix'' has been to just deal with the situation. One thing we did do
was recompile some screen intensive programs and lower their priority.
Recompiling will only help marginally, but hey every little bit...
