FMS 2 closing connections

I see the client still listed in the FMS Admin Console. The connection dies off after a minute or so, but thats too late because it obstructs the other connections trying to publish with the same stream name.

The code for the swf is listed below, the connection is not reopened.

The important point is the connection stays alive even when the client's browser window is closed.

--
nc = new NetConnection();
nc.connect("rtmp://gimme.homelinux.net/livecast/");
ns = new NetStream(nc);
mycam = Camera.get();
mycam.setMode(600, 400);
mycam.setQuality(25600, 0);
//mycam.setQuality(0, 0);
mymic = Microphone.get();
mymic.setRate(11);
ns.attachVideo(mycam);
ns.attachAudio(mymic);
ns.setBufferTime(0.1);
ns.publish("abc", "live");

nc_tv = new NetConnection();
nc_tv.connect("rtmp://gimme.homelinux.net/myliveapp/instance1");
ns_tv = new NetStream(nc_tv);
myvid.attachVideo(ns_tv);
ns_tv.play("mylivestream", -1);
ns_tv.setBufferTime(0.1);



//startstop_pb.enabled = false;

connect_pb.onRelease = function(){
if(this.label == "Connect"){
status_txt.text += "Connecting..." + newline;
this.label = "Disconnect";
nc.connect(rtmp_txt.text);
} else {
mymic.clear();
myvid.clear();
ns.attachVideo(null);
ns.attachAudio(null);
ns.close();
nc.close();
nc.close();
ns_tv.close();
nc_tv.close();
}
}

startstop_pb.onRelease = function(){
if (this.label == "Start Broadcast"){
status_txt.text += "Starting broadcast" + newline;
this.label = "Stop Broadcast";
ns.publish(streamname_txt.text, "live");
} else {
status_txt.text += "Stopping broadcast" + newline;
this.label = "Start Broadcast";
myvid.attachVideo(null);
myvid.clear();
ns.close();
}
}
