Probably don't want the two extra PetscSFView() calls (lines 1687, 1688)
though- presumably they were just for temporary debugging?

I think it fixes your problem.
Thanks very much Matt, that does fix it. Good stuff!

This is typical for weak preconditioners. Have you tried -pc_type gamg
or -pc_type mg (algebraic and geometric multigrid, respectively)? On a
structured grid with smooth coefficients, geometric multigrid is
possible with low setup cost and convergence in a few iterations
independent of problem
