This feature protects your server from giving up when another game bug, the "telnet flood" brings your server to the knees. If your server is quite full it often happens that telnet gets out of control and the game sends an unending "Cannot send package to client" message. This gets extrme until the point that the tool as well as the server gives up.
Therefore this feature detects this telnet flood and initiates and automatic restart of the game. So you can sleep safe again ;).
In the config you can activate the function. Just check the "Telnet Flood Restart"
