protein relax

I am trying to relax my protein with ligands FMN before do further design. I used movemap to exclude the rotamer on FMN. my flag and movemap file looks like below. I also attached my protein_FMN pdb. It takes an extremely long time and it seems like stuck somewhere (I attached the screen shot). Is it normal and anybody knows why? Thanks

flag file:

-in:file:s ./input/3TX9.A_FMN_Crystal.pdb

-in:file:movemap movemapfile

# Harmonic runs

-relax:constrain_relax_to_start_coords

-relax:ramp_constraints false

-relax:coord_constrain_sidechains

-relax:coord_cst_stdev 0.5

-out:path:pdb ./output

-out:path:score ./score

-out:suffix _harmonicrelax

-nstruct 1
