You are doing a structure optimization via MSR1a (-min)
Why should the optimization stop when -cc is fulfilled ?
It will continue until the forces are small enough and the atoms are not
moved much anymore.
:FRMSA shows that your 2 mRy criterium is not fulfilled 3 times in a
row, because atoms are still moving.
Since :ENE is still decreasing, I'd let it run until :ENE does not
decrease anymore.
PS: Termination of a MSR1a minimization is a bit tricky and not always
"save". In some cases it converges much too good (final forces much
smaller than the requested 2mRy, in others it can be that it seems to be
converged, but after stopping the atoms the converged forces might be
bigger than the 2mRy.
It depends a lot on your system, but your molecule seems to be "simple".

Any suggestion or just wait a little ?
Thank you !
