Open the "Memory" Control Panel from the Apple menu, then click the Virtual Memory "On" button and set the size to at least "120M". Quit other open applications and run Unreal Tournament again, or increase the amount of Virtual Memory in the Memory Control Panel. If you use Ram Doubler, you may need to increase the "Minimum Size" memory setting on the Unreal Tournament application.
