There is nothing wrong, it is converging slowly and my guess is that
it will need 60-80 iterations as you currently have it modelled. If
you have only run it for 20 iterations, do another 20 and use the -NI
option so it keeps going. DO NOT RESTART from dstart.
N.B., the forces are not meaningful unless you have "FOR" instead of
"TOT" and the densities are much better converged than this.
