Yes, this is a known problem. With a high number of collisions ode creates a 
huge matrix to solve it. This will surely crash your application. Windows 
users will suffer the most from this problem because windows has a static 
stack size.
If you want to simulate a large number of objects colliding you could use 
stepfast. I managed to collide hunderds of balls with stepfast with no real 
problems on my 2.6Ghz laptop (except overheating :-) )
