failing job:err 300

[jadefox337]

Dear all,

I am attempting for the first time to run a geometry optimization for
large data set with periodic boundary conditions.  My data set is
large - 225 atoms and I never did PBC.  My job fails with the
following message:
____________________________________________________________

Can someone advise on where should I start looking for the problem
(other that the code itself - with which I am not really familiar).

Thanks you,
