Erm, in this case there's no reason for nmbd to be running on your system at
all and I'm not sure why it ever *started* successfully in the first place.

nmbd will refuse to run when there are no broadcast interfaces present on
the system, and lo is obviously not a broadcast interface.

It seems not; there have been various bug reports in the past of users
having nmbd problems because of their interfaces not being continuously up,
but with your settings this isn't the problem.

FWIW, listing both 127.0.0.0/8 and lo should be redundant; you should be
able to just list 'interfaces = lo' and get the same results.

- which results, as mentioned, include nmbd not working right.  So given
that you don't have a wins server specified, which would be the only other
eason to have nmbd on, I'd suggest setting 'disable netbios = yes' in your
smb.conf as a workaround that will stop nmbd from running, sparing you from
any further mails.
