Server Config Information

Default LinuxGSM installs have configSubDir=servername set in the command line which will set your priority config files to be in /home/user/serverfiles/KFGame/Config/kf2server directory, use these files to change settings on your server.

Workshop Content

Killing Floor 2 supports Steam Workshop.

High disk IO using Steam Workshop

Killing Floor 2 will check workshop files at server start and when map changes occur.

There is a potential problem with Killing Floor 2 servers using the steam workshop that causes server disk usage to read/write at 100% and could damage hardware.

To avoid this problem keep the amount of workshop content as low as possible.

Disk IO can be monitored with the ioptop command.
