CPU Exception errors

Hello Managers,

I got paged this morning when /var went past 95% (thank god for that AdvFs
feature), and I tracked down the problem to be the /var/adm/binary.errlog
file. Using uerf, I was able to see its contents. As far as I can tell (the
file was > 975MB), all the entries were similar to the following:

----- UNIT INFORMATION -----

UNIT CLASS CPU

********************************* ENTRY 174.
*********************************

----- EVENT INFORMATION -----

EVENT CLASS ERROR EVENT
OS EVENT TYPE 100. CPU EXCEPTION
SEQUENCE NUMBER 3.
OPERATING SYSTEM DEC OSF/1
OCCURRED/LOGGED ON Fri Jun 4 00:02:27 1999
OCCURRED ON SYSTEM yoda
SYSTEM ID x00070016
SYSTYPE x00000000
PROCESSOR COUNT 2.
PROCESSOR WHO LOGGED x00000001


Running a uerf -o terse showed me the following:

CPU EXCEPTION: UNKNOWN SYS TYP


Does anyone know what might be causing it? By the rate of growth of the
/var/adm/binary.errlog file, I project that it started some time late last
night. How can I fix this problem? What do I look for to prevent it from
happening again? The log continues to grow, and I am catting /dev/null to
it every few hours. This is a Alpha 4100, 2CPU, 2GB RAM, running Tru64 UNIX
4.0D. Any points are appreciated.
