Servers randomly stop?

[denizkoekden]

Hello,
I didn't want to open an Issue for this. I guess its something easy to fix. I have some Servers thats work fine but then after some time they get shut down. In the debug or latest-log there is no sign of an error but I only find this:

[05May2023 08:52:30.179] [Server thread/DEBUG] [net.minecraftforge.common.ForgeHooks/WP]: Gathering id map for writing to world save world [05May2023 08:52:30.185] [Server thread/DEBUG] [net.minecraftforge.common.ForgeHooks/WP]: ID Map collection complete world [05May2023 08:54:04.623] [RCON Listener #2/INFO] [net.minecraft.server.rcon.thread.GenericThread/]: Thread RCON Client /127.0.0.1 started [05May2023 08:54:04.625] [RCON Client /127.0.0.1 #3/INFO] [net.minecraft.server.rcon.thread.RconClient/]: Thread RCON Client /127.0.0.1 shutting down [05May2023 08:54:04.676] [Server thread/INFO] [net.minecraft.server.MinecraftServer/]: Stopping the server [05May2023 08:54:04.719] [Server thread/INFO] [net.minecraft.server.MinecraftServer/]: Stopping server [05May2023 08:54:04.720] [Server thread/INFO] [net.minecraft.server.MinecraftServer/]: Saving players [05May2023 08:54:04.720] [Server thread/INFO] [net.minecraft.server.MinecraftServer/]: Saving worlds

and then the whole MC shutdown sequence...

Any idea what that could be? Is the healthchecker doing something? The players is not shutting down the server.

It's hard to say what's happening. Something on your system is telling the container to stop. Check your system level logs and run a docker inspect on the container to see if it provides any clues.

We have a System that checks if the Server has query and if there is no query from the server it stops the server. The question is: Why is the no query from the server?

I found what is happening but ATM I don't have a solution to that problem.

Everytime I add a new netns to the server, all Docker containers loose their netns and so their network breaks. The netns I add has its own IP address and so I don't now what's happening their. I will experiment further with that intel I got from digging 😅...

I fixed this issue. I deleted orphan regular netns and the docker netns looked like orphans to my script...
