Akos, One way to get around this duplication problem when labeling polygons is to create a point file of polygon center points and style the points so they are transparent, but are labeled with the name of the polygon.
This will not solve the problem of missing labels, however. If the label is split I assume it would be left off, unless you manually move the points that suffer this indignity. Let me know what you think of this idea. I am a new user of GeoServer, so I do not speak from experience.
