1. Install Arma 3 dedicated server (legacyports branch) using SteamCMD:
```
Steam> app_update 233780 -beta legacyPorts -betapassword Arma3LegacyPorts validate
```
2. Run the server with mod(s); strace part is for more logging:
```
$ cd ~/Steam/steamapps/common/Arma\ 3\ Server
$ strace -ff -o /mnt/memdisk/arma3server ./arma3server -netlog -ip=192.168.153.1 -port=2302 -cfg=/home/arma3server/Steam/steamapps/common/Arma\ 3\ Server/cfg/arma3-server-modded.network.cfg -config=/home/arma3server/Steam/steamapps/common/Arma\ 3\ Server/cfg/arma3-server-modded.server.cfg -mod=mods/@rhs_afrf4 -servermod=mods/@rhs_afrf4 -bepath= -loadmissiontomemory
4:20:08 SteamAPI initialization failed. Steam features wont's be accessible!
$
```
3. Server crashes right after start (that is, in matter of seconds)
