Comment (by rhaas):
This may well be the same issue as with the single NS #2118, namely having to set {{{GRHydro::sources_spatial_order = 4}}} since http://einsteintoolkit.org/gallery/bns/nsnstohmns.par does not set it and the default is 2. Admittedly normally a too low order should be more dissipative and should lead to an earlier merger but still, having and order of 2 makes little sense. One would have to go back and check whether at the time the example was created (by me) GRHydro used {{{ADMBase::spatial_order}}} or {{{GRHydro::sources_spatial_order}}}.
