Thank you for your quick response,
I'm starting the server over the provided "run.bat" file.
And the total amount of RAM, I calculated with the amount of RAM used and the percentage of unused RAM in the Java GUI, is that not accurate?
I'm running a Minecraft Forge 1.17 server but I can't add more RAM to it.
I can change the amount of RAM to 4G and it launches without problems, but the the Java GUI tells me it's still running on 2G.
Before you comment, yes I have entered the -Xmx4G into the new "user_jvm_args.txt" document.
The computer I run the server on has 6GB of memory (I know, rare sight) so it should run just fine.
If you need any more information, I'm happy to oblige. Thanks in advance!
