My server keeps attempting to startup but then just ends up going offline

[mcmaster]

I have no idea why this keeps happening and I need help as of why this is happening and how to fix it. Before it shuts down I get this in console 

/home/minecraft/signal/start_cmd: line 1:  2498 Killed                  /opt/java/17/bin/java -Xmx${SERVER_RAM} -XX:+ParallelRefProcEnabled -XX:MaxGCPauseMillis=200 -XX:+UnlockExperimentalVMOptions -XX:+DisableExplicitGC -XX:+AlwaysPreTouch -XX:G1NewSizePercent=30 -XX:G1MaxNewSizePercent=40 -XX:G1HeapRegionSize=8M -XX:G1ReservePercent=20 -XX:G1HeapWastePercent=5 -XX:G1MixedGCCountTarget=4 -XX:InitiatingHeapOccupancyPercent=15 -XX:G1MixedGCLiveThresholdPercent=90 -XX:G1RSetUpdatingPauseTimePercent=5 -XX:SurvivorRatio=32 -XX:+PerfDisableSharedMem -XX:MaxTenuringThreshold=1 -DIReallyKnowWhatIAmDoingISwear -Djline.terminal=jline.UnsupportedTerminal -Dlog4j2.formatMsgNoLookups=true -jar server.jar
