Please need your help. I run excitation state geometry optimization for Covalent Organic Framework COF (truncated part). Molecule having total 98 atoms including NH3 molecule atoms in gaseous form. I have tried many times with td-dft B3LYP/631-g (d) and other keys Scf= (maxcycle=700, conver=6) and gfinput gfprint, but could not get normal termination. Server stops jobs without showing any error termination.
