I might be able to confirm this but not fix it.

I had a dual nic NFS server (both nics in the same subnet and physical lan)

I was issuing a mount to nic1, but nic0 was responding, so I got the NFS
NULL call and a timeout.

The fix was to issue it to nic0.

(This is very likely due to my same subnet setup)

Work like you don't need the money,
love like you'll never get hurt,
and dance like nobody's watching.
