Removing Too Many? Or possible duplicates...

I know that when you remove the same object twice, the client will crash. I think that may be happening here. But the range is only 0.05, so I'm not positive. Ok, I generated a list of every object around the point 500, 500, 0 in a radius of 1000. This totals an amount of 3318 objects. The default ackslimit gave me warnings (because it is only 3000/second), and I crashed when connecting. I raised the ackslimit to 4000/second, same (crashed again).



So is it crashing because multiple of the same object are in the range of 0.05? Or is it because too many are removed at once...?
