On one of my worlds, the internal server of minecraft stopped working. My client was running fine, but the internal server stopped responding. I could not take damage, enter commands, use the chat, use tile entities, and when i broke blocks in survival, they did not drop. This internal server lag does not seem to affect other worlds, but cannot be removed from the one world. It is fix or delete world at this point.

Attaching it. I notice a continuous OpenGL error during the first second or two of the lag. Then, when the lag stops, the server skips about 100 ticks. Interesting. (I have worked with the code of Minecraft before, as I sometimes make mods. But do not worry, this is not the result of one of my crazy projects!)
Please attach the complete output of the "Development console" which can be found on the second tab of the launcher.
If the launcher closes after game start, please edit your profile and select "Launcher visibility" then, "Keep the launcher open".
