Are you really sure you did not mess with NFS at some point (maybe via
an automounter)? You might even want to reboot, as this will at least
clear any mount-ish confusion in the system.
If this message is logged at the same time every day, tcpdump(8) might
at least confirm that the box is, indeed, trying to do NFS. Ideally, it
could also give at least a little insight into what it's trying to do.
Finally, try showmount(8) and nfsstat(8) - they might help point you to
the problem.
