Problem Mindcrack Server Freeze

[CurvedSteel1]

Alright,

So I made a server a few days ago.

I started playing a bit and everything was fine

Now I keep getting disconnected with:
Internal Exception: Java.SocketTimeoutException: Read Timed Out

After I get disconnected, my Server freezes

I went through the Server logs and found this:

[SEVERE] Encountered an unexpected exception NoClassDefFoundError
java.lang.NoClassDefFoundError: l
at a.<init>(CrashReport.java:27)
at a.a(CrashReport.java:319)
at net.minecraft.server.MinecraftServer.r(MinecraftServer.java:672)
at ho.r(DedicatedServer.java:270)
at net.minecraft.server.MinecraftServer.q(MinecraftServer.java:598)
at net.minecraft.server.MinecraftServer.run(MinecraftServer.java:497)

What is wrong and how can I fix this?

Any help would be greatly appreciated

Hard to say, can you upload the whole server log / crashlogs / console logs to pastebin orso. The Error above can be to many things

Sorry lol, I'm new to this

This is my Client Log:
http://pastebin.com/zjZpjX9u

I got the information from a server.txt file in my server folder

I uploaded the Crash Report that I later found in my Crash-Reports Folder XD
