Spigot 1.8

Server running on a raspberry pi 2 with the command: sudo /opt/jdk1.8.0_60/bin/java -Xms512x1008M -jar /home/minecraft_1.8/spigot-1.8.jar nogui (1008M since 16M is dedicated to GPU)

1-5 players on server, view distance even at 2. Entering nether takes around 10 seconds and then loads. Exiting gives everyone an "Internal Exception: ionetty.handler.timeout.ReadTimeoutException", with the server console saying " Garzhod lost connection: Internal Exception: java.io.IOException: Broken pipe". If multiple players on, will kick all players.

With or without any plugins will cause the same issue.
