It looks like it's a generation error. Try loading a singleplayer world. Many users don't because that isn't their problem, but it helps us know where your problem is, with the server, or the client. In this case, besides being out of memory, you are also having world generation errors by the looks of it. Start by increasing your allocated RAM, and then try in SP.
