Machine Check while PAL mode?

» close window

The Question is:

 
I have an alpha 800 running VMS 7.2-1
every other morning i come in to find it has shutdown and has the following
 message on screen....
 
Halted CPU 0
Halt code = 7
Machine check while PAL mode
PC=c100
>>>
 
I have installed the lates Firmware 5.7
Do you have any idea what this may be?
Nothing in the Operator log ??
I have been unable to find anything in WIS.

The Answer is :

 
  Please see topics (1038), (2829), (3562), (4582), and (6129).
 
  If you set the the console environment variable:
 
    SET AUTO_ACTION RESTART
 
  The next incident of this should trigger a MCHECKPAL system
  crash (bugcheck), followed by an automatic reboot.
 
  And as stated in the topics listed above, a machine check error
  is most likely a result of a hardware problem.  Please contact
  your hardware support organization.
 
  Your hardware support organization may (will?) request the
  output from the above-mentioned crashdump file:
 
    $ ANALYZE/CRASH SYS$SYSTEM:SYSDUMP.DMP
    CLUE ERRLOG
    [CTRL/Z]
    $ DIAGNOSE CLUE$ERRLOG
