Hi,

I have random server stoppings (soft crashes), so I decided to clear all my errors from log.
I'm using PaperSpigot 1.18.1 #103 build
I'm hosting server on i7 6700k with 32GB RAM. This server have Xmx5G. Next error is showing on server start:

[16:45:20] [Server thread/ERROR]: [Vault] [STDERR] SLF4J: No SLF4J providers were found.

What the hell is going on in there

@Geolykt I would like to know that too. Before reporting this problem I tried on clean server with PaperSpigot 1.18.1 build 103, with only Vault plugin, same error. I am no java expert, but I think it has something with log4j fixes.

@AngelDeaD this means that the logging provider was removed from the server. We don't bundle a logging plugin with Vault that's why it's complaining about not being able to find one. It's possible that Minecraft/PaperSpigot, in their haste to fix the log4j2 issue broke logging for mods. I don't think there's a good way to fix this error message right now other than by making sure there's an slf4j provider in the server.
