Greetings ,comrads.
I have game with this code(zero gravity):
<img src="https://dl.dropboxusercontent.com/u/95062274/pics/rub2.png" border="0" />
and this on scene (black lines shows physics connections):
<img src="https://dl.dropboxusercontent.com/u/95062274/pics/rub3.png" border="0" />
When this construction collides with borders, all construction start vibrating like this:

How to make strong connections without this effect ?
