Memory Issue

[austere stratus]

Actually your java args seem to be set to use 8, I guess it failed to allocate around 2GB...

[tacit mica]

strangely your jvm is also 64 bit

[austere stratus]

Thats usually the issue, yeah

[tacit mica]

please try downloading a different distribution ,adoptium java instead

[austere stratus]

Not this case

[tacit mica]

ive seen plenty of nonsense from ms openjdk

like memory access violations from glfw

[tacit mica]

are you.. in mc?

[obsidian mica]

it starts

but randomly gets that crash

midgame

like after 10 minutes of playing

[tacit mica]

im even more confused

since

it says youve allocated 8GB

[obsidian mica]

yeah i read the error log and was confused myself

after the first time i thought like ok ill just allocate more

but same crash on 10 and 12

[austere stratus]

Sounds like a memory leak which causes an OOM crash, although the threaddump here is unusual for that

Allocating more than half your system memory is not really recommended

Use too much and your computer suddenly does not have enough memory to function

Maybe it is related to the swapfile?

[obsidian mica]

i did put in some arguments

[austere stratus]

Which ones?

[obsidian mica]

just the aikar ones but that was for another modpack

i removed them and am playing for like ~8 mins rn

wait ill send them here

-XX:+UseG1GC -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 -Dusing.aikars.flags=https://mcflags.emc.gs -Daikars.new.flags=true

could this be the cause

i don't know what these settings even mean

[tacit mica]

no its not because of that

please try removing your java

and installing adoptium temurin

[obsidian mica]

okay i think i know why

[tacit mica]

whys that

[obsidian mica]

the moment i activated screen share

to discord

it instantly crashed

i usually stream gameplay to my friends

[tacit mica]

🤨

[austere stratus]

I assume you were streaming the app vs. Your full screen?

[obsidian mica]

i was streaming minecraft specifically

in windowed mode

[austere stratus]

Either way, it might actually just be that you flat out run out of memory then

Discord screenshare is surprisinly heavy

Just have task manager open next time you try

[obsidian mica]

allright

[austere stratus]

The fact is if your memory goes to 100% and your game tries to allocate more memory, it has to rely on swap, or crash

[obsidian mica]

ahh makes sense

i think all the times where it happened randomly i started stream in the main menu of the game

so after 5 min of playing it died

i just now did it while playing in server and it just instantly went poof

[austere stratus]

F

[obsidian mica]

thanks for the help noaaan and frontear

most modpack* servers u get ignored

[austere stratus]

No worries 👍

[pseudo wharf]

I fixed this problem cause no one was helping me here on this discord.

go ahead like i just did it, learn about all mods in the modpack and check that ones that "help" with the performance in the game.
