Comment 106 for bug 607560

Wrong again, got exactly the bad behaviour on Ubuntu 13.10. It's perhaps not related to the issue that started this thread, but since I posted here I thought I might as well inform anyone visiting this that my solution didn't work.

My current thinking is that if you have an NFS4 server with clients attached, and you reboot the server without detaching the clients, you get the bad behaviour. If you umount the clients first, then reboot the server, then mount the clients, the problem doesn't occur.
