Server not starting (Segmentation fault, Ubuntu, Docker)

[P4sca1]

Hello all,

I try to run a gmod server on my Mac with Docker. I created an image, based on ubuntu 16.04, which installs needed dependencies to start the server. Now, when I start the server with the server files mounted from my Mac, the server just crashes, showing the following information:

Sat Apr 21 01:17:56 UTC 2018: Server Quit

This is how I start the server:
docker container run -it --name gmod -v /Users/pascal/code/gmod-server:/gmod p4sca1/egm-server:gmod

Here's the bash script belonging to the container (some useless echos for debug atm):
DEBUG=$(printenv DEBUG)
INSECURE=$(printenv INSECURE)
IP=$(printenv IP)
PORT=$(printenv PORT)
SLOTS=$(printenv SLOTS)
MAP=$(printenv MAP)
TICKRATE=$(printenv TICKRATE)

echo $DEBUG #todo
echo $INSECURE #todo
echo $IP
echo $PORT
echo $SLOTS
echo $MAP

cd /gmod
./srcds_run -game garrysmod +ip $IP -port $PORT -maxplayers $SLOTS +map $MAP -tickrate $TICKRATE -nohltv -norestart +r_hunkalloclightmaps 0 -debug -insecure

The directory of the mounted files looks like this:

Any hint, why the server can't start is appreciated.

Kind Regards,
Pascal
