According to section 2.3.3 of Jong-Kyu's thesis discusses internal boundary conditions at rational surfaces. He brings up how DCON systematically eliminates the large solution near rationals, which is necessary for mercier unstable perturbations to integrate to integrate to a finite delta W. However, for the purposes of perturbed equilibria, the large solution is a valid solution, and we are needlessly throwing it out. Enabling this solution should be investigated.
