seem that this is also on the vannilla server, this just happened to me aswell, trying to find a fix, if i can will post here. Edit: It appears that this is a problem with the chunks in some way, i removed all entities and any unused chunks (as well as the pistons and redstone i was using when it gave this crash) with MCEdit and that let me run the map again as normal.
