I just saw one almost the same as this. When I did an nfsv3,tcp mount I
got a similar message, but it was for the NFS NULL RPC.

I left it and after a while it retried and succeeded.

I tried rebooting the client and server a couple of times, but wasn't
able to get it to happen again.

So, I wonder if what the others were seeing was something similar? rick
(ps: I'm running a current kernel and nfs related utilities, but really
old Feb. userland for the rest.)
