back-end: Spigot 1.12 build #1316
front-end: Waterfall build 124 https://ci.destroystokyo.com/job/Waterfall/
Spigot suddenly throw this exception while running normally:
[10:02:13] [Netty Server IO #0/WARN]: Selector.select() returned prematurely 512 times in a row; rebuilding Selector io.netty.channel.nio.SelectedSelectionKeySetSelector@13cb56f5.

Right after that all online players are kicked out immediately:
[10:02:13] [Server thread/INFO]: k_jiang lost connection: Disconnected [10:02:13] [Server thread/INFO]: k_jiang left the game [10:02:13] [Server thread/INFO]: Nchyns lost connection: Disconnected [10:02:13] [Server thread/INFO]: Nchyns left the game ......(and similar messages about other players be kicked out)
Then all players are no longer be able to join the server again. This issue already happened twice today. I could only resolve this issue only by restarting the server from the console.
No other error occur on Spigot or on the Waterfall (BungeeCord) side, no matter during server start, running or shutdown.
