Server crashing infrequently due to 'out of memory' warning

Spark profiler thinks the server is using 8gb, but the server panel thinks it is using nearly 20. Which is correct? Trying to ID why the ram usage is so high.

More ram = better, surely

ProGamingDk•2y ago

no more ram = usually worse

:HOPIUM: Contrary to popular belief, less is more What's better, eating just enough that you're happy, or so much that you're sick?

Doesn't pterodactyl show how much is allocated instead of how much is being used? Thats just smth I heard somewhere, could be completely wrong

Zaid•2y ago

I wouldn't rely on it usd tps command instead I believe it was

ProGamingDk•2y ago

essentials has /memory and spark has a method aswell

Sorta. All system reporting shows what is reserved by the JVM. What's reserved is marked as in use to the system, but that doesn't mean the minecraft server is using it. System reporting = task manager, pterodactyl panel, top command, etc.

1who¡ssus?•2y ago

What's the crash report?

Discount Milk•2y ago

Well, I think that's debatable. Generally has been shown to be effective in helping though.

ProGamingDk•2y ago

Discount Milk•2y ago

Use aikar flags

java -Xms8G -Xmx8G --add-modules=jdk.incubator.vector -XX:+UseG1GC -XX:+ParallelRefProcEnabled -XX:MaxGCPauseMillis=200 -XX:+UnlockExperimentalVMOptions -XX:+DisableExplicitGC -XX:G1HeapWastePercent=5 -XX:G1MixedGCCountTarget=4 -XX:InitiatingHeapOccupancyPercent=15 -XX:G1MixedGCLiveThresholdPercent=90 -XX:G1RSetUpdatingPauseTimePercent=5 -XX:SurvivorRatio=32 -XX:+PerfDisableSharedMem -XX:MaxTenuringThreshold=1 -Dusing.aikars.flags=https://mcflags.emc.gs -Daikars.new.flags=true -XX:G1NewSizePercent=30 -XX:G1MaxNewSizePercent=40 -XX:G1HeapRegionSize=8M -XX:G1ReservePercent=20 -jar server.jar nogui

(AlwaysPreTouch has been removed)

MarijnIsN00B•2y ago

I did have it, removed it and it was still happening

Discount Milk•2y ago

Didn't say that it removes it entirely, just that it is effective to help 👀

MarijnIsN00B•2y ago

I just spent a few hours downloading the entire server to my own pc and reinstalled the server, now Imma try again and hope it finally works like normal Yeah just the thing is, before upgrading my server I never had this crash happen I used the same flags and after the upgrade this shitshow just constantly happened
