DEC EVENT results



       Below are the results of our DEC EVENT run and there are some
errors that keep coming so often. Unfortunately we don't know how to
interpret the same error messages. We are running Digital Unix version
4.0F.

Can anyone interpret the messages. What is the problem with our system ?

Thanking You In Advance (TIA),

Masa.
