	If you are using Mono 2.6.x or earlier, you are out of luck. If you are running 2.8+, try running mono with SGen (generational garbage collection) enabled, like this: <code>mono --gc=sgen ServerCLI.exe</code> or <code>mono-sgen ServerCLI.exe</code>. If you've tried everything and cannot get Mono memory usage under control, try setting the [[List_of_config_keys#Advanced\|RestartInterval]] config key to make the server restart itself every once in a while.

			To join a server that's hosted on the same machine, you have two options:
			# Add <code>?override=true</code> parameter to the server URL: [http://www.minecraft.net/classic/play/____________________?override=true http://www.minecraft.net/classic/play/____________________?override=true] ( fill in the blank with your server hash).
			# Connect to your server directly, by IP/port: [http://www.minecraft.net/classic/play?ip=127.0.0.1&port=_____ http://www.minecraft.net/classic/play?ip=127.0.0.1&port=_____] (fill in the blank with your port number).

Fortunately, there is a workaround:		Minecraft client has a lot of trouble working on LAN. You probably will not be able to connect via the public URL. Fortunately, there is a workaround:
	# Enable "Allow connections from LAN without verification" checkbox in ConfigGUI's "Security" tab (or set [[List_of_config_keys#Security\|AllowUnverifiedLAN]] to "true" in ''config.xml'').		# Enable "Allow connections from LAN without verification" checkbox in ConfigGUI's "Security" tab (or set [[List_of_config_keys#Security\|AllowUnverifiedLAN]] to "true" in ''config.xml'').

	# Find ~~your~~ local IP address.		# Find the local IP address of the server:
	#* In Windows XP+, go to Start -> type "cmd" to open a terminal -> type <code>ipconfig</code>.
