Getting many errors "SIGSEGV: invalid attempt to write memory at address"

[Stingrrr]

Hi,

The server seems to be running, and I am able to connect, but I lose connection after just a couple of minutes.

There are several folders in the Crashes folder now, and they look like this:

I guess this is the reason I'm losing connection, can't find anything in the logs about client logins/crashes.. Any idea what the problem is?

[Stingrrr]

Do I do anything with the Dockerfile that's in the repo by the way?

[noamyoyo]

seems like u don't have enough memory, how much is allocated?

[Stingrrr]

I don't know 😅 How do I check that? The server has 24 GB ram.

[Stingrrr]

Is allocating memory something I have to do on the Palworld server or in docker? When I do docker container stats I get this:

[noamyoyo]

Oh you're on oracle free tier too?

[noamyoyo]

Memory looks fine, can u share your docker compose?

[Stingrrr]

Yeah it's free tier. I use the same docker compose as on the front page on this repo (Getting started section)

version: '3.9'
services:
  palworld-server:
    image: 'nitrog0d/palworld-arm64:latest'
    container_name: 'palworld-server'
    ports:
      - '8211:8211/udp'
    environment:
      - ALWAYS_UPDATE_ON_START=true
      - MULTITHREAD_ENABLED=true
      - COMMUNITY_SERVER=false
    restart: 'unless-stopped'
    volumes:
      - './palworld:/palworld'

i am getting the same error

[jwxxzc]

might possibly be an issue that was solved previously. I will attempt this later, hopefully you can try it out and see if that's the problem. https://github.com/nitrog0d/palworld-arm64/issues/16

[jwxxzc]

Fixed for me

[noamyoyo]

@Stingrrr yeah make sure u have the right permissions, especially if u try to use older saves that u imported into the game files

[jwxxzc]

@Stingrrr try sudo chown -R 1000:1000

like below in that directory

[Stingrrr]

@jwxxzc That fixed it for me too! Thank you all for the help!

And thanks @nitrog0d for the image! 😃
