[gmx-users] MPIRUN error while running position restrained MD

Thanks for the mail. Yes, I solvate the protein and
then do a EM with steepest descent and then I proceed
to do position restrained MD, first restraining the
protein and then the backbone. It is at the backbone
restraint step I got this error. Also I assumed that
if there are any bad contacts they would get resolved
in minimization step, but looks like it hasn't. Please
tell me how to solve this problem.
