for medium and large systems, it is usually much better to use
direct SCF and integral-direct integral transformation thus avoiding
storage bottlenecks.

Use $scf dirscf=.t. $end and $trans dirtrf=.t. $end

On a separate note, it is very bad idea to disable FSF.
Leave FASTF option at its default value (the default is .true.)

Hope this helps.

Kind regards,
Alex Granovsky
