  I got one response in this, from "Paul M. Aoki" <aoki_at_CS.Berkeley.EDU>,
who has had the same problem with 3.2.
I got my final solution my calling Dec and getting a mega patch set for
OSF/1 3.2 which included a patch for this problem.
Here is Paul M. Aoki message and my reply, which describes the patch I
applied :

  Thanks for the info. I had also found that there was a
patch for later versions of the OS, but I can't update at this time
unfortunately. I ended up calling Dec support and they put a mega
patch for 3.2 in an ftp area for me. I found the patch I needed in there.
I think it is this one but I applied about 20 different patches from
the set, so I am not sure :

System hang or system panic with "kernel memory fault" if an nfs server
is given corrupted data.

 I have Dec 3000/500 alpha running Digital Unix 3.2, which started having
a problem booting today after a power failure.
It seems to boot fine until it gets to the
nfs server programs (mountd ...). then it dumps with the error:

dupdone: bad copy 0c8d28ec00 0
panic(cpu 0): svcudp_dupdone


 The only mention I can find of this errors indicates it could be:

The Patch ID is:
=======
PROBLEM: (Patch ID: OSF350-020) (HPAQ72013)
System hang or system panic with "kernel memory fault" if an nfs server
is given corrupted data.
=======

 Since this patch is not For OSF3.2, and I cannot find the patch anyway,
it does not seem to apply to this situation. Does nayone know what this
error might be from, and what I need to do to fix it?
