I have noticed now on several occasions that the server is accepting connections but dropping them immediately.
It seems to happen after the server has been up and running for a day or 2 accepting connections normally.
I have noticed this in several game slots and with local and remote connections. Any existing connections are working fine until the player logs out.. and then they cant get back in.
The problem seems to be consistent once it starts..
Closing the TWGS server and restarting it fixes the problem..
I have only noticed this behaviour recently, since 2.07 i think..

I wonder if anybody else has experienced the same problem...

If you are getting a "Failed to start game session..." message before it disconnects, then the answer is yes. If you are using putty, you have to set "Close window on exit" to never or you won't see the message before the window closes. Microbot has seen this on several servers.

no i am using swath.. and i hadnt seen this problem previously.

From our teamspeak chat, this does not appear to be the same issue I have seen as the server is dropping connections on connect. The other issue doesn't happen until teh player tries to launch a game.
