When BWCC was carried out for a molecule, after MR_BWCCSD had converged a correction began, but there were many steps showing Warning:Denominator is very low.
What should be taken to make the calculation continue?

| A slight increase of the size of the basis set used makes the calculation finish, and the activation barrier calculated is only a bit better than that obtained by CCSD implemented in GAMESS but worse than any other by CCSD level above coupled cluster method therein, whether in ROHF or RHF.
