Uncontrollable spinning

[jb485]

Hi, I've attempted to make a simple testing environment for bullet with a few simple cubes (btRigidBody with btBoxShape) floating around in a box (made up of 6 * btStaticPlaneShape). However, whenever a cube touches the side of the box (or any other cube) it starts to immediately spin very fast and never loses energy. I experimented by setting restitution to zero and although that makes it slightly less bouncy, the mad spinning is still there. Any ideas?

EDIT: this doesn't seem to happen if I use btBoxShape for the walls instead of btStaticPlaneShape.

jb485, make sure that rigidbody in not bigger than the box. I suppore, that planes are bad choice, because they're infinite
Boxshape should be fine, if you need exactly box shape.
Consider also trimesh with normals inwards.
