Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0 Flash Player 9, Flash Lite 4

The MemoryError exception is thrown when a memory allocation request fails.

On a desktop machine, memory allocation failures are rare unless an allocation request is extremely large. For example, a 32-bit Windows program can access only 2GB of address space, so a request for 10 billion bytes is impossible.

By default, Flash Player does not impose a limit on how much memory an ActionScript program can allocate.

MemoryErrorExample.as

The following example shows one method of generating a MemoryError.
package {
    import flash.display.Sprite;
    import flash.errors.MemoryError;
    import flash.utils.setInterval;
       
    public class MemoryErrorExample extends Sprite {
        private var crashingStr:String;
        private var intervalId:Number;
           
        public function MemoryErrorExample() {
            crashingStr = "abcdefghijklmnopqrstuvwxyz";
            intervalId = setInterval(exhaustMemory, 50);
        }
           
        public function exhaustMemory():void {            
            try {
                crashingStr += crashingStr;
            }
            catch(e:MemoryError) {
                trace(e);
            }
        }
    }
