The optimization is running (I don't know slowly or quickly, it's depends).
Note, the max atomic forces and siesta E_KS energy decrease as a function of cycles number (although there is some increases).

I think it's ok (I didn't see the optimization parameters. But I think you are using a high DM. tolerence (1.d-5) compared with a low MessCutoff.
I would recomend you to increase meshcutoff.

I am doing force minimization using SIESTA and my calculation is still running (more than 4 days) i think this is convergence problem. Can any one help me in this regard. I have attached mu output file.

With regards
