    Description

      When I start a server, the server loads normally, but once a player joins the game, the server console begins spitting out

      [Netty Epoll Server IO #1/WARN]: Unexpected exception in the selector loop.
      io.netty.channel.unix.Errors$NativeIoException: epoll_wait(..) failed: Function not implemented
      

      This causes the tps of the server to tank and makes the server unplayable as a result.

      Tested the server on both java 17 and java 18, both openjdk binaries with the same results
