the code listed in the stack trace you posted runs when the current client is in a room with a foreign client, and then the foreign client leaves the room. the current client learns of the foreign client's departure via a u37 UPC, which triggers some cleanup code in the room that the foreign client just left. unfortunately, i have not been able to reproduce the error you posted. the use case of a foreign client leaving a room is extremely common in union applications, and therefore deeply tested, so the error is very likely a remote edge case. nevertheless, we'd like to track it down if possible.

could you please post a code example demonstrating what lead to the error you encountered?

thank you for reporting this issue. i'm marking it solved until we can investigate with example code. if you post example code, please unsolve this post.

I have the same problem, however I only get the error half the times. The other half it works well. What I'm doing is basically
-There are 3-4 players in a room (which is a lobby room)
-Room is set to die when empty
-If a player presses the start button, it sends a message to the whole room, and the message listener from every client "starts the game"
-They join a new room, named after the previous room + the ID of each player stringed together.
-They load the map
-They leave the previous room

And here's where I get the error. The following is the debugging right before the error happens.

Code: Select all

I tried re-creating the error in an isolated case, however it didn't work. This, coupled with the fact that it works half the time has led me to believe that it has something to do with the Game/Map being loaded. Maybe some clients are lagging behind, leading to this whole situation.

the moment I removed this reactor.getClientManager().removeEventListener("CLIENT_DISCONNECTED", ClientGone, false); problem fixed

protected function ClientGone(e:ClientManagerEvent):void
{
var client:IClient = e.getClient();

if (getUserName(client) == "system")
{

}
}
