             I am new to Gromacs & using it with Amber force field amber03,
i am able 2 run my system of DNA till steepest descent but when i tried to run it for cg it showed that can not work with so much of constrains so i tried to run it with -Dposres

Minimization with position restraints serves very little, if any, purpose in my mind.

directly to mdrun with md integrator it showed an error message "wrote pdb files with previous & current co-ordinate segmentation fault." how can i modify my mdp file to overcome this problem ?

Your system is insufficiently minimized and/or equilibrated. Please see the following:
