Version?

  • legacy41_61 and public

 

Singleplayer/Multiplayer? 

  • Multiplayer

 

Host or dedicated? 

  • Dedicated

 

Mods?

  • No

 

Reproduction steps:

 

legacy41_61 branch:

  1. Download the server software using SteamCMD 
    // Set the game installation directory
force_install_dir /home/steam/ZomboidDedicatedServer

login anonymous

// Install/Update the Zomboid Dedicated Server
app_update 380870 -beta legacy41_61 validate

quit

     

  2. Attempt to set the maximum JVM RAM to 6 GiB using the `start-server.sh` file. 
    #!/bin/bash
#

  3. Run the server by running the above modified file.
  4. Observe that the server is only ever allocated 2048 MiB of RAM from the server logs:

  5. Server then crashes when attempting to use more than 2GiB of RAM.

 

public branch:

  1. Download the server software using SteamCMD 
    // Set the game installation directory
force_install_dir /home/steam/ZomboidDedicatedServer

login anonymous

// Install/Update the Zomboid Dedicated Server
app_update 380870 -beta public validate

quit

     

  2. Attempt to set the maximum JVM RAM to 6 GiB using the `start-server.sh` file.
     
  3. Discover during the previous step that those settings don't exist.

My workaround has been to also modify the `ProjectZomboid64.json` file when running the server on the `legacy41_61` branch. This makes the following appear in the startup logs, which is more promising: 

64-bit java detected

I have also verified that in the above configuration, the server can happily exceed the 2GiB RAM limit.

 

I was informed that a "logged in" Steam user downloads a different `start-server.sh` file to the one that a dedicated server receives.  I believe that a user hosting the server from within the game (non-dedicated) receives the following `start-server.sh`: 

#!/bin/bash

INSTDIR="`dirname $0`" ; cd "${INSTDIR}" ; INSTDIR="`pwd`"
JARPATH="./:./istack-commons-runtime.jar:./jassimp.jar:./javacord-2.0.17-shaded.jar:./javax.activation-api.jar:./jaxb-api.jar:./jaxb-runtime.jar:./lwjgl.jar:./lwjgl-natives-linux.jar:./lwjgl-glfw.jar:./lwjgl-glfw-natives-linux.jar:./lwj>

if "${INSTDIR}/jre64/bin/java" -version > /dev/null 2>&1; then
        echo "64-bit java detected"
        export PATH="${INSTDIR}/jre64/bin:$PATH"
        export LD_LIBRARY_PATH="${INSTDIR}/linux64:${INSTDIR}:${INSTDIR}/jre64/lib/amd64:${LD_LIBRARY_PATH}"
        JSIG="libjsig.so"
        LD_PRELOAD="${LD_PRELOAD}:${JSIG}" "${INSTDIR}/jre64/bin/java" \
                -cp "${JARPATH}" -Djava.awt.headless=true \
                -Xms2048m -Xmx2048m -XX:+UseZGC \

                -XX:-OmitStackTraceInFastThrow -Djava.security.egd=file:/dev/urandom \
                zombie/network/GameServer "$@"
elif "${INSTDIR}/jre/bin/java" -client -version > /dev/null 2>&1; then
        echo "32-bit java detected"
        export PATH="${INSTDIR}/jre/bin:$PATH"
        export LD_LIBRARY_PATH="${INSTDIR}/linux32:${INSTDIR}:${INSTDIR}/jre/lib/i386:${LD_LIBRARY_PATH}"
        JSIG="libjsig.so"
        LD_PRELOAD="${LD_PRELOAD}:${JSIG}" "${INSTDIR}/jre/bin/java" -client \
                -cp "${JARPATH}" -Djava.awt.headless=true \
                -Xms768m -Xmx768m \
                -Dzomboid.steam=0 -Dzomboid.znetlog=1 \
                -Djava.library.path=linux32/:./ \
                -XX:-OmitStackTraceInFastThrow -Djava.security.egd=file:/dev/urandom  \
                zombie/network/GameServer "$@"
else
        echo "couldn't determine 32/64 bit of java"
fi
exit 0

This is quite different to the one I am served on the `public` branch.

 

Can you investigate whether "logged in" Steam users hosting non-dedicated servers are being distributed different files to dedicated servers downloading using the 'Steam anonymous user'?

Use the json file to set parameters for the exes, which the script calls. None of the stuff after exit 0 is reached. It was removed in subsequent versions. 

 

Build 61 doesn't include many fixes and should not be used.

 

Anonymous should always be used for the dedicated server package. Very odd that the scripts are different.

Thank you for getting back to me.

I was so busy reading the JVM args, that I honestly didn't notice that sneaky `exit 0` in between the calls.

So your suggested approach for altering JVM args is via the JSON files? 
I will make sure to update my image with that.

 

Thanks again, and happy holidays!
