 A reference moment value times the tolerance is used by the  Newton-Raphson method for checking convergence.  The calculated  reference MOMENT CONVERGENCE VALUE = 5.114045982E-03 is less than a  threshold.  This threshold defaults to 1.0-2 or is specified as MINREF  on the CNVTOL command.  Check results carefully.
