aaah ... I missed that notice in the documentation.  I've replaced all
the places in my code where I did this:

  NcAtt* elev = ncfile.get_att( "Elevation"  );

with

  std::auto_ptr<NcAtt> elev =  ncfile.get_att( "Elevation"  );
i.e delete this when it goes out of scope ...

and have restarted the program, will let you know if the resource
problem shows up again.

thanks for the help.
