Maps seems stuck while enumerating structures

Alloy Theoretic Automated Toolkit (ATAT)

Hi,

At the beginning, MAPS works just fine and generates about 3-4 structures for VASP calculations.
After this (all DFT converges), MAPS is not able to generate new structure(s) even after 4 days.
Could you please advice?

Here is my lat.in:

You will get significant speed improvement if you use the most primitive cell possible. To find it:
mv lat.in lat.in.org
cellcvrt.exe -s < lat.in.org > lat.in

You can also constrain maps to NOT generate too large supercell with the -mv option (say, -mv=24 ) .
Note that versions 3_23 and later have a speedier enumeration algorithm.
