There are several problems using x86_64 linux NFS (v4) machines as server, and

For now there are this issue yet known (linux 2.6.13+CITI, Linux 2.6.14-rc*
+CITI)
-> Socket error -11 closing a big file (server : x86_64, clients: x86, ppc64)

-> Oops (Client x86_64, server x86_64) - Linux 2.6.13+CITI

However, this issues concern NFSv4. I am going to try to reproduce your
problem with NFSv3 and NFSv4.

I've not heard anything negative about x86_64 systems as NFS servers, but this note is somewhat concerning to me as I've got some new AMD Opteron hardware coming to replace some Pentium 4 NFS servers.  We only use NFS v3 (mainly tcp).  Should I be concerned?  Should I use i386 mode instead of x86_64?
