The NFSv4.1/4.2 server generates a console message that indicates
that there is no session. I was until recently perplexed w.r.t. this
could occur. It turns out that the common cause is multiple NFS
clients with the same /etc/hostid.
The host uuid is used by the FreeBSD NFSv4.1/4.2 client as a unique
identifier for the client. If multiple clients use the same host uuid, this
indicates to the NFSv4.1/4.2 server that they are the same client and
confusion occurs.
This trivial patch changes the console message to suggest that the
client's /etc/hostid needs to be checked for uniqueness.
The review is simply for the wording of this new console message.
