About once a day, all workers crash and bring down the server with the following error message:

Running LuckPerms Bukkit 4.4.1 on Paper build 238 for MC 1.14.4.

You're fairly outdated as LuckPerms v5 was released already.

Muirrum · Answer 2 · 2019-12-31T20:43:43.000Z

I updated to v5 and I'll see how it goes.

Scheduler system was changed in v5, yeah.

Although, there's nothing wrong with the log output you posted - that's totally normal. You'd need to focus on the "Server thread" bit to see why the server is timing out.
