SWF randomly fails to load - doesn't throw ioError

programming flash

I have this class:


    public class LogoManager extends Sprite{
        function LogoManager(x){
            var loader:Loader = new Loader();
            
            function loaded(evt:Event){
                trace('worked');
                addChild(evt.target.content);
            }
            function failed(evt){
                trace('failed');
            }

            loader.contentLoaderInfo.addEventListener(Event.COMPLETE, loaded);
            loader.contentLoaderInfo.addEventListener('ioError', failed);
            loader.load(new URLRequest(x+'.swf'));
        }
    }

Periodically, it fails to load the swf, which is weird because the swf is a local file. If it fails, it doesn’t call the failed function, or the loaded function.

Does anyone know why it would work sometimes and not others? Is it just a bug that happens when I run it locally? Will it still break o the server? Is there a good way to check for and handle it – maybe a different error message it is throwing, or some way to retry after X seconds?
