Bruno Chareyre proposed the following answer:
The wall is stable.
The apparent problem is because bodies 80-82 have only translations blocked (not rotations as in xyzXYZ), hence they are taken into account in the unbalanced force (and the total force on the bottom plate is not supposed to be zero of course). With full  fixities unbalanced force goes to 0.
It also appears that you are using an extremely small timestep, which makes the stabilization very slow.
