Hi,

I have three AlphaStations (2x 500/500, 1x 500/400) running
Digital UNIX 4.0B. When I do 'uerf -R' I get the following
error on all machines :

********************************* ENTRY 1. ----- EVENT INFORMATION
-----
EVENT CLASS ERROR EVENT
OS EVENT TYPE 100. CPU EXCEPTION
SEQUENCE NUMBER 4.
OPERATING SYSTEM DEC OSF/1
OCCURRED/LOGGED ON Fri Jun 20 13:05:06 1997
OCCURRED ON SYSTEM struct5
SYSTEM ID x0007000F
SYSTYPE x00000000
----- UNIT INFORMATION -----
UNIT CLASS CPU

On two of the three machines this happens from time to time :
     
first machine
OCCURRED/LOGGED ON Fri Jun 20 13:05:06 1997

second machine

OCCURRED/LOGGED ON Mon Mar 10 10:17:06 1997

but on the third machine this happens a lot :

third machine

OCCURRED/LOGGED ON Fri Jun 27 21:36:43 1997
OCCURRED/LOGGED ON Fri Jun 27 11:08:45 1997

Does this mean there is a hardware (cpu) problem on all
machines? Only on the third machine? Any info will be greatly
appreciated.

Thanks in advance
Bart.
