Dear Managers,
All my humblest apologies for my rather unclear summary.
A more complete version appears below.
It WAS a memory problem. I called
the guys at Digital support and they gave me the info I needed to
find out what module was the culprit.
The UERF utility does not parse the error entries
properly and mistakes memory errors for cpu errors. From the
information I received from the Digital guy I found out that the
machine was trying to report uncorrectable memory errors.
Thanks to the following for pointing me in the correct
direction.

No one was able to tell me where I may obtain documentation on
how i may go about analysing that information for myself, though.
My original question was:
Hello managers,
I am writing again to enlist your aid in solving a very
perplexing problem. I have an AlphaServer 2100 machine running
Digital Unix 3.0b with 512 MB of RAM and 8 RZ28 disk drives and
the machine is filling up its binary errorlog file
(/var/adm/binary.errlog) with entries of the form:

I have the full error report from the system corresponding to the
output from the command uerf -R -o full -c err . I did a check
to see how many entries like this there were in the file and
found 3085 such entries all recorded in a space of 5 minutes.
The binary errorlog file has grown to over 400 MB in size!!!
I have replaced the CPU module and the problem still seems to
occur as of 15-Jul-1996 09:00:00. Any ideas?
Also, can anyone suggest to me where I may obtain
documentation to allow me to analyse these error entries for
myself?
