HELP!! Internal exception: java.io.IOException: Received string length longer than maximum allowed (1337>64) Error message! Please help!
So i was just playing on my bukkit server and then this message popped up: java.io.IOException: Received string length longer than maximum allowed (1337>64) I looked at the console and saw that everyone else on the server disconnected too. I somehow managed to get pasw the error message, but i found out that if i passed this certain part of my world, I would get the error message. I spawned some sheep on the part of the world that i kept getting the error from, but the sheep were just acting normally. Please HELP! (P.S.) i have a mac and i am running a 1.6.4. server even though 1.7.2 came out.)
