So you suffer from periodic crashing? Then read on!
Since Killing Floor was based on the Unreal 2004 engine, it was only designed to be able to use a maximum of 2 gigs of ram as per the restrictions of windows XP and the 32 bit operating system therein.
With our highly modified and substantially more taxing use of custom scripts and spawns on the server, it uses a lot more ram. As a consequence, once we go over the 2 gig threshold... BAM. Crash.
