The warning in the MD calculation

Dear cp2k users,

When I do a MD simulation, there are two warning in each SCF calculation?
Could you give me some advice?

 ===== Routine Calling Stack ===== 

            8 set_mo_occupation_1
            7 set_mo_occupation_2
            6 scf_env_do_scf_inner_loop
            5 scf_env_do_scf
            4 qs_energies_scf
            3 qs_forces
            2 qs_mol_dyn_low
            1 CP2K
