Ok, so that rules that out. What are your mount options? Can you get a quick trace of this? If you use tcpdump, write out to a file, and use a 0 snaplength to make sure you get the rpc section of the packet. Is the problem reproducable, or is it constant?
Did this start after any specific change, or has this always been this way? Can you capture a perfstat?
I'll look at the perfstat for nfsclient and filer nfs server specifics for problems. nfsstat and netstat output for transport or lower layer issues. Well let's start there, and see where that leads us.

We are seeing extremely high network traffic from single clients to nfs mounted filers. In most cases running nfswatch on the client shows almost all of the traffic due to "RPC Authorization". We are talking 50-80Mbits of traffic with nothing sticking out on the clients process list. Has anyone seen weird high network traffic via nfs over udp?
