Hello Dave, and thanks for responding.
Alrighty then. Looks like it's time for a little more experimentation. I'm
going to turn off both rpc.lockd and rpc.statd on this (and the others)
and see if the NFS service(s) work a little more as intended. If it does,
that'll be great. But doesn't cure an /apparently/ ailing NFS. I'll report
back on my findings here.

FWIW for anyone that might be interested; I am willing to make this boxen
a guinie pig/lab rat in an effort to discover what might be wrong in the
NFS family of services in FBSD. If interested, let me know what needs to
be done.

Thanks again for responding.
