So I have a server called CrimsonnMC and whenever I start it up it crashes after about a minute. I have no idea what the cause is, the only thing I know is that this never happened before. I also have the crash logs so I hope anyone can find a fix to it. /home/minecraft/signal/start_cmd: line 1: 1961 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 -jar server.jar

Whenever i leave my server and then rejoin it after it has stopped and started again, my progress is lost from when it was last started, this is only a recent thing as it hasnt been happening on my smp world for at least 2000 ingame days so im really confused to why it is broken now and please help because i have a lot of progress on my server and dont want to see it wasted because i have to reset my world or anything so please help if possible so that my progress can be saved again.
