Is this a memory hole or just my bad code?

programming flash

Now I’ve removed my previous idiot’s mistake (‘why has this stopped working’, below), my kiosk program runs fine - for a while.

It’s set to go to remove all eventListeners, go to frame 2, load and play a random f4v if the mouse isn’t moved in a preset interval. after the video’s finished it removes the stream and goes back to the main program on frame 1.

This all appears to work fine for about 20 minutes on a 10 second timer, however the program crashes after about 20 minutes regardless of whether the program plays as an SWF or executable.

My guess is that this is because I’m not clearing everything out in each loop, and that there’s a build-up that eventually clogs the program and it falls over, but I can’t see anything more that I can do to clean up.

The code for frame 2 is as follows:

stop();
import flash.display.MovieClip;
import flash.events.Event;

var poseList:Array=["cold.f4v","rubNeck.f4v"];

var poseNo:Number = Math.round(Math.random()*(poseList.length-1));
var randPose:String=poseList[poseNo];

var video_vd:Video = new Video();
video_vd.x=0;
video_vd.y=0;
video_vd.width=1080;
video_vd.height=1920;

var connection_nc:NetConnection = new NetConnection();
connection_nc.connect(null);
var stream_ns:NetStream=new NetStream(connection_nc);
stream_ns.addEventListener(AsyncErrorEvent.ASYNC_ERROR, asyncErrorHandler);
stream_ns.addEventListener(NetStatusEvent.NET_STATUS, netStatusHandler);
video_vd.attachNetStream(stream_ns);
addChild(video_vd);
stream_ns.play("poses/" + randPose);
//stop the stream immediately so we can buffer in advance
stream_ns.pause();
//set the video back at 0 start
stream_ns.seek(0);

//every 500ms execute the function checkLoaded with param = stream_ns
var loaded_num:Number=setInterval(checkLoaded,500,stream_ns);

function checkLoaded(my_ns:NetStream) {
	//calculate the percent loaded    
	var percentLoaded:Number=Math.round(my_ns.bytesLoaded/my_ns.bytesTotal*100);
	//If the video has loaded completly then resume playing the movie
	if (percentLoaded>=100) {
		stream_ns.resume();
		clearInterval(loaded_num);
	}
}

function netStatusHandler(event:NetStatusEvent):void {
	//trace(event.info.code);
	if (event.info.code=="NetStream.Play.Stop") {
		stream_ns.close();
		removeChild(video_vd);
		video_vd = null;
		gotoAndStop(1);
	}
}

function asyncErrorHandler(event:AsyncErrorEvent):void {
	//trace(event.text);
}

The asynErrorHandler code seems to be neccessary even though the f4vs are created (supposedly) without metadata in After Effects.
