Servers lingering in server list

[Shifty Geezer]

I have a list of servers populated on a button press. At the beginning of the scene (main menu) I stop servers in the Start call. However, when I then press the server search button, the terminated server is still present and will remain until a few seconds after termination.

1.         void Start () {
2.                 if(TNManager.isInChannel){
3.                         TNManager.LeaveAllChannels();
4.                 }
5.                 if(TNServerInstance.isActive){
6.                         TNServerInstance.Stop ();
7.                 }
8.                 ...
9.         }
10.  
11.         public void UpdateServerList(){
12.                 // populate with available servers and show when button pressed
13.                 serverList = TNLobbyClient.knownServers.list;
14.                 while (serverGrid.transform.childCount > 0){
15.                         NGUITools.Destroy(serverGrid.transform.GetChild(0).gameObject);
16.                 }
17.  
18.                 if(serverList.Count == 0){
19.                         twn_noGamesFound.PlayForward ();       
20.                 }else{
21.                         for(int n = 0; n < serverList.Count; n++){
22.                                 ServerList.Entry ent = serverList[n];
23.                                 go = NGUITools.AddChild (serverGrid.gameObject, serverEntryPrefab);
24.                                 go.transform.GetChild (0).GetComponent<UILabel>().text = ent.name;
25.                                 go.name = ""+n;
26.                                 go.GetComponent<UIDragScrollView>().scrollView = go.transform.parent.GetComponent<UIScrollView>();
27.                         }
28.  
29.                         serverGrid.transform.parent.GetComponent<UIScrollView>().ResetPosition ();
30.                         serverGrid.Reposition ();
31.                         serverGrid.transform.parent.GetComponent<UIScrollView>().ResetPosition ();
32.                         twn_noGamesFound.PlayReverse ();       
33.                 }
34.         }

Assuming you're using a UDP server lobby link, it's the expected behaviour. UDP updates are periodic and don't have an established connection that has a way to identify when it was closed.
