Well, I believe that it's the "SleepToFast" bug that makes such stacks possible.
Let's hope that this bug is fixed in the next Tokamakrelease.
You could apply a minimal impulse(like 0.00001) to some of the objects to keep them awake. That should make them fall.
However that is a workaround and is only a temporary solution until the bug is fixed.
The ability for a body to "fall asleep" is one of the essential things that keeps the simulation as fast a possible.
