Sorry, I intended the subject to make that clear, the client is CentOS-5 the 
server FC16. The message appears on the CentOS5 client. The same server and data 
works on clients running FC9, FC10, FC13, RHEL-6, and I believe (ie. I'm told 
but haven't personally tested) OpenBSD works as well.

This is the only machine which stopped working when the NFS server was updated, 
and of course it's the internal web server. :-(
