I have problems with the barells again...

I want to pile up them, but I want them to bounce a little, when collide with something, so I set their bounciness property to 0.3f. The problem is, that if I set any value to bounciness, they are shaking and moving all the time...

Can I somehow set some sensitivity or other thing that prevent the applying of bounciness under a given border value?
Maybe is there any other solution?
