Description

Basically every few minutes, all the users from the server get the ''Timed out'' screen and it crashes with the LuckPerms log.

Reproduction steps

1. Have LuckPerms v5.1.26 along with PaperSpigot 1.8.8
2. Wait a few minutes
3. See error

Expected behaviour

Well, the server not to crash after a few minutes.

Environment details

PaperSpigot 1.8.8 + ViaVersion (Dev build)

• Server type/version: ExampleSpigot running version 1.12.2 build ???
  LuckPerms version: v5.1.26`

Crash error: https://pastebin.com/D9DqG1qE

Any other relevant details

You are quite a number of builds behind, see if it still happens with the latest one https://luckperms.net/download

Also, keep in mind that stack trace you pasted isn't necessarily an error. The crash log includes information from all threads running on the server, and since LuckPerms does most of its work asynchronously, you will probably see a lot of them. If anything, please provide the entire crash log and the whole server log as well (located in logs/latest.log) :)

Nothing there to suggest LP is the cause of a crash
