Public bug reported:
After a recent upgrade on my clients to Ubuntu 13.04 latest and Ubuntu
12.04.03 on the server, NFS4 clients began locking up with the errors
below. Processes accessing NFS would hang up and lock, and could not be
killed or adjusted. NFSv3 on the same server and client has been
working fine.
NFS4 was configured with clean defaults, no special options set. No log
entries corresponding with the problem were seen on the nfs server.
