Run Unity apps on Linux

Running CentOS 6 server. Tried running my server app using this way: http://answers.unity3d.com/questions/353653/can-a-unity-game-be-started-over-ssh.html

Here's what I'm getting though:

 [root@xxx lobby]# xvfb-run --auto-servernum --server-args='-screen 0 640x480x24:32' ./lobby -batchmode
 Set current directory to /root/glorious/lobby
 Found path: /root/glorious/lobby/lobby
 Mono path[0] = '/root/glorious/lobby/lobby_Data/Managed'
 Mono path[1] = '/root/glorious/lobby/lobby_Data/Mono'
 Mono config path = '/root/glorious/lobby/lobby_Data/Mono/etc'
 /usr/bin/xvfb-run: line 166:  1902 Aborted                 (core dumped) DISPLAY=:$SERVERNUM XAUTHORITY=$AUTHFILE "$@" 2>&1

Logfile:

 [root@xxxlobby]# cat log.txt

 Debug info from gdb:
 
 
 =================================================================
 Got a SIGSEGV while executing native code. This usually indicates
 a fatal error in the mono runtime or one of the native libraries
 used by your application.

Anyone got any ideas?
