start the server and stop it with the stopp command. if that doesn't work try opening it in MCEdit and then using the chunk cleaner ( idk how much that would help ) and if all else fails use a backup.
Delete the "World" folder. It's in the same location as your craftbukkit.jar file. Also delete the "World_Nether" folder if it exists. WARNING: This will erase everything on the map, make a backup if you have things on there you don't want to lose!
