Greetings !

Scenario : Alphaserver 8400, HSZ70, RAID5, DU 4.0B Patch #7

A vdump is taken on a cloned filesystem (base7, a database location),
while there is a fair amount of activity on the database (don't know
specifically about the activity on this location). And then, suddenly...

>From DECevent :

SWI Minor class 9. ASCII Message
SWI Minor sub class 1. Panic

ASCII Message panic (cpu 0): can't pin page
                                      N1 = 5

base6 and base7 are two domains sharing a physical disk (I know this is not
recommended
but it worked well for about half a year). We don't discard hardware
problems, but this is
a RAID5 volume, so I guess it should not handle a failure in this
catastrophic way.

This is 4.0B patch #7, does anybody know if there is another patch available
for this kind of problem ? Of course I'll summarize.

As usual, many thanks in advance,
