Most likely nobody can answer this question, because nobody understands your question.
At least I did not understand what you are really doing.
Did you run x optimize with option 7 ?
Did you modify optimize.job or just run it unmodified ?
Did you put min_lapw instead or run_lapw ?
Did you find the structure with lowest total energy ?

Why would you run again an scf ? You already have one ?
