Hi

I cannot see any problematic behavior when running a similar
system (you don't give us your exact input).
Could it be that the additional SCF iterations you see, are just the
finite difference calculations from the numerical stress evaluation?
BTW why not using the analytic stress evaluation?
Also, if you are using DFTB and periodic boundary conditions I would
strongly advice to use EWALD!

regards
