Too many bitmaps?

programming flash
1

I’ve been working on a simple mosaic generator for a project and have been crashing Flash consistently by trying to add too many bitmaps to a Sprite. I can crash Flash every time with the following:

for(var i:int = 0; i < 10000; i++){
var d:BitmapData = new BitmapData(20,20);
addChild(new Bitmap(d));
}

I get a 2015 error - invalid BitmapData.

9000 works without issue… 10000 crashes. Problem is I need 10000.

Is this a known limitation? I could try using multiple sprites and adding say 5000 to each, but that wouldn’t be easy with this project. But if I have to I have to…
