Description of Problem: I'm running a server and everything was going great until i built a collector out in the desert with a redstone pump on some gold pipe coming out of it, suddenly the server crashed, now every time I move toward the area where i built all that, and the server tries to load that chunk, it crashes the server. It doesnt close the server program, its just done and needs to be closed and restarted.
Error Messages: In game/ minecraft not on server it says Connection Lost
Internal exception: java.net.Sockettimeoutexception: read timed out
I posted the server log from start to crash also.
