Hi Adrian,

Barry and Mark's suggestions will make this go away. However, it should not
happen
in the first place. We should try to figure this out.

This warning is usually activated by the -options_left argument. Could that
be in the
PETSC_OPTIONS env variable, or in ~/.petscrc?

  Thanks,

What most experimenters take for granted before they begin their
experiments is infinitely more interesting than any results to which their
experiments lead.
