Out of interest, has the NFS issue been tested on NFS4? My understanding is that NFS4 has a lot of fixes for the locking/caching problems that plague NFS3, and we were planning to use NFS4 from day one.
I've tried with Linux NFS4 server+client a few years ago. It seemed to have all the same caching problems as NFS3.
If this hasn't been tested, is there some kind of load simulator that we could run to see if the issue does occur in our environment?
http://imapwiki.org/ImapTest should easily trigger it. Just run it against two servers, both hammering the same mailbox.
