rigid body go throughout wall

Hi,
i have roller(stl import) and 1 granular atom inside. I use "moveStl all move/mesh/gran rotate" in it's axis.
It's all OK.

Then i need uneven atom so i make one rigid body from 102 atoms. And now rigid body go throughout the roller.. Why? What i make wrong?

atoms for rigid body are read with read_data. My data for read are someting like this:

data.rigid

102 atoms
1 atom types
-3 4 xlo xhi
-3 4 ylo yhi
-3 4 zlo zhi
Atoms
1 1 1.9 3620 -0.404 0.188 0.895
2 1 1.9 3620 -0.95 -0.309 -0.04


I think rigid body it's much heavy. So i try give all atoms in data.rigid density = 1. And i make one bigger atom which covers most of atoms and it's density = 3600. like this:

data.rigid

10 atoms
1 atom types
-3 4 xlo xhi
-3 4 ylo yhi
-3 4 zlo zhi
Atoms
1 1 1.9 1 -0.404 0.188 0.895
2 1 1.9 1 -0.404 0.188 0.895
2 1 6 3620 0 0 0

But situation has not changed.

Thanks for answer
