Subject: AMBER: No skew or curtosis when zero variance in moment

Dear Amber users£¬

        I saw the error message "No skew or curtosis when zero variance in moment" when I calculate the entropy lost during ligand binding using MM/PBSA. I refered to the mailing list, but found no useful info. Unluckily I got a positive vibrational entropy change, which seems to be unreasonable.
Is there anyway to solve this it?
¡¡¡¡¡¡¡¡¡¡
