There is likely something different about the system you minimized
and the one you are doing MD on. Make sure the the potential energy at the
beginning of the MD run (-15181) matches that at the end of the minimization.

It might be that all you need is more minimization, but your symptoms are
those of a more fundamental problem, but we don't have enough information
to say that that problem is.

You didn't say if you ran the job in serial mode or not. Be sure to do that
if you have not already done so.
