-I had (and reported to IBM) this problem several months ago.
-How slow, or if fast, how loaded is your NFS server? I was running Unix
-on a 4meg 386sx-16 as a server, and when using 8000 byte NFS packets, I would
-get corrupted data after a copy or xcopy. I didn't have any problems at all
-when I copied to/from a 386DX-25. Dropping the packet size to 4K fixed
-the problem. I just upgraded my server, and was going to try 8000 byte
-packets again. There goes that idea I guess.

I was told by NFS tech support that the max buffer size
can only be 7168, the reason being that IBM NFS uses part
of that buffer for some internal suff.
Has anyone ever been successful with NFS and larger ( > 7168 )
buffer size?
So what is the story with the latest CSDs (Base: 32131, NFS:32132),
should they be avoided?
