OK, I found -ksp_error_if_not_converged will trigger PETSc to fail in this case.

I met a case where MUMPS returned an out-of-memory code but PETSc continued to
run. When PETSc calls MUMPS, it checks if (A->erroriffailure). I added
-mat_error_if_failure, but it did not work since it was overwritten by
MatSetErrorIfFailure(pc->pmat,pc->erroriffailure)
Does it suggest we

To reiterate what Matt is saying, you seem to have the exact solution on a
10x10 grid. That makes no sense unless the solution can be represented
exactly by your FE space (eg, u(x,y) = x + y).
