So sometimes with my server I get this issue where the server won't start without me validating rust server and then updating rustoxide. I have now pinpointed it down to the Discord extension itself. Maybe I'm wrong, I just don't have any more info in the logs :/ - whenever I remove plugins that do not use Discord, then the server starts.

[EDIT: ended up having to remove extension itself to get rid of startup hangs]

[EDIT2: removing and adding discord ext back allowed it to start again] [Really sucks that I cant get constant error reproduction]

If I add Discord Extension back then the server will start up to ~4.7kb of log size and then hangs. Server process has to be killed in order to restart.
Regarding more logs.. the oxide log just shows my plugins loading as such: Loaded plugin....

And the log just suddenly stops after it has loaded all the plugins. Hence the hang..

Here is console.log:

I'm not seeing anything in this log file indicating an issue. Is that as far as it gets into the startup process?

The actual issue from what I can tell is: Unable to preload the following plugins: libRenderer.so

That isn't related to Discord though, and there are some existing threads on that issue. Generally this issue comes down to not having a path set.

Yes this is as far as it gets. The server also started up when librenderer failed to reload so there is something else up.

Sucks to have an issue you cant troubleshoot. I suppose this thread can be closed if nothing can be done about the issue.

Do you have the library path set for Linux?

https://github.com/OxideMod/Oxide.Rust/blob/4d1def91f86d535a5d69f5c9e2573007e71660ae/resources/_start-example.sh#L2

This is the LD_LIBRARY in runds.sh script which linuxGSM uses. 

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:`dirname $0`/RustDedicated_Data/Plugins/x86_64

./RustDedicated -batchmode -logfile 2>&1​

Yes, got the server setup with linuxGSM. Do you think I should take it up with them? If so, might you have a hunch what I should be asking them more precisely?

I think LinuxGSM is a common factor in this issue, but I don't see why it would be other than many Linux users use it.

Ended up writing a script that will validate and mods-update the server if it hangs on startup. It will loop through it until it starts - does the job :)
