Command i use to start the server: sudo java -Xmx6G -jar server.jar nogui

OS: Debian 12 (Linux)

RAM: 8G
Has anyone had this problem before? I looked it up and saw a few comments on how it could possibly be because i installed the x86 bit version of Java but i don't think that's the case, as it says it is 64-bit when I enter java --version into terminal (command prompt)
Either way, heres the output for the java --version command

java 21.0.5 2024-10-15 LTS
Java(TM) SE Runtime Environment (build 21.0.5+9-LTS-239)
Java HotSpot(TM) 64-Bit Server VM (build 21.0.5+9-LTS-239, mixed mode, sharing)

I'm running 1.21.4, Spigot (buildtools) and have a few plugins installed

- PluginMetrics (automatically installed with buildtools)

- floodgate
- bStats (automatically installed with buildtools)
- Geyser-Spigot
- Chunky (specifically for this problem)
- ProtocolLib
- Essentials

Please help me fix this problem it is extremely annoying to fly with elytra when it can't load any chunks

I wanted to put a /tp command into a command block, and allow other users who are not an operator to be able to use it, by stepping on a pressure plate and teleporting them to the place I directed the /tp command to send them.

Is there a way to do this?

I have one mod installed into a 1.7.10 minecraft forge server. I have Forge 10.13.3.1400, 1 mod I am trying to load

https://www.curseforge.com/minecraft/mc-mods/timetraveler

and 3 Gigabytes allocated to the server. Here is the crash report:

Any ideas?

I have frequently made a Minecraft Java server using this server pack:

https://www.curseforge.com/minecraft/modpacks/zombie-apocalypse-slow-zombies-by-forge-labs/files/3249178/additional-files

and upon using the search box in JEI the game crashes me, but no other players on the server.

Heres a crash report of what happened:

I tried updating JEI to the newest version for 1.12.2 but that did not work

I tried adding more ram to my minecraft server

I tried to see if it happened to other players, it did

Can't seem to find any information on what might be causing the crashes. Any ideas? I really appreciate any help you can provide.

I'm not understanding completely, but have you tried creating a normal world and then adding resource packs?

I figured out the problem. It was because 1.8 doesn't create a run.bat or user_jvm_args.txt. Instead you are supposed to run the forge universal.jar, although instead of being a .jar file it turned into a .zip linux. Instead I created the server on Windows 11 and it seemed to work just fine

I am following all the directions of a guide to start a modded Minecraft Java Server on Debian 12 (Linux)

I installed forge, and then installed the server in a specific folder I made just for the server.

Once finished, in the tutorial he says to use the command "ls" (I am making the server using terminal) I am missing a file to start my server, run.bat, and user_jvm_args.txt

I can't find any information on this problem, and I don't know what I'm doing wrong

Here is a little more information:

The tutorial on how to make the server

The part where I get stuck at in the video: 24:55

The commands I used to get forge:

wget https://maven.minecraftforge.net/net/minecraftforge/forge/1.8-11.14.4.1563/forge-1.8-11.14.4.1563-installer.jar

and

java -jar forge-1.8-11.14.4.1563-installer.jar --installServer

Please help me, if you need any more info just ask in the comments

Haha Kk

not enough ram probably

you need to install the plugins that are the same version as the server's version

It did not work, any other ideas?

Ok thanks, I'll try that

I have started a new Minecraft Java server in Debian 12 (Linux) and downloaded the Pixelmon Mod to go with it. The server itself runs fine, but the Pixelmon mod has a lot of problems. One of the people I know joined the server and every time they try to attack and kill a pokemon, it gives us this error saying that the battle could not be completed and they earned no xp for battling that pokemon

I have tried to look up a few different things on Google but couldn't find anything to solve my problem. Does anyone know a solve to this?

Did that work? I am having the same problem where it crashes the server. I will disable bosses if this worked for you
