It has just spontaneously happened, and it seems everyone is being kicked from the server. It is a dedicated server, so I can't change the Java version on the server, but it was running perfectly beforehand, so I can't think what may have happened.

Any ideas?

PS. Editing the layout of this OP as we speak.

This happens to me too but in specific areas of the world where players have been building. I'm guessing something has been built or has caused this to happen from bugs in the mods?
