* C:/Windows/SERVIC~1/NETWOR~1/AppData/Local/Temp/IronGate/Valheim/Crashes

Steps to reproduce:

  • Step 1
  • Step 2
  • Step 3

Actions taken to resolve so far: i tried updating the instance and the server, nothing seems to work.

Same happend to me, too.
My server runs AMP “Decadeus” v2.4.3 on Ubuntu 20.04.06 LTS

What i observed is that roughly 10 files, each around 1.3GB were created in the server root directory shortly before the server stop working. The naming for the files is something like “core.xxx” where xxx represents numbers. The files do not appear in a non valheim-plus installation:

Any ideas on what I can do to fix it? It’s driving me bonkers trying to figure it out.

Are you missing any dependencies that are required to run valheim? Mayve Microsoft C++ redistrobutables? Latest supported Visual C++ Redistributable downloads | Microsoft Learn
