[comp.unix.ultrix] silo overflow message points to wrong device/port

gordon@prls.UUCP (Gordon Vickers) (03/02/88)

    Ever since I installed Ultrix 2.0 (two weeks ago), I have been
  occationally getting the error message:
        dz1.4: silo overflow
    The real source of the problem seems to be dz0, port 3 .
    Looks like the discrepancy is just a differance in numbering
  conventions.  The source of the error messages apparently numbers
  devices and ports by starting with "1" , whereas /sys/conf/MYVAX
  specifications start with zero.

   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...
