Hello,
sorry for my late response, I've been working in something else and didn't have time to check this out. I have tested what you told me. Well, half tested. I didn't where to put 'Partials=true' (in sld file or in map file at layer level??), so I didn't put it anywhere, and also removed from my SLD the tag '<VendorOption name="group">true</VendorOption>', just to see what could happened, and it worked perfectly. Just to understand a little bit, can you make a short explanation of why do I have to do this to make it work. Also, where do I have to put 'Partials=true' if it's necessary?? Take into account that I work with external SLD files and not with layer inner style.
Once again, thanks.
Un saludo,

David,
Try using
"labelcache_map_edge_buffer" "-10" at map level WEB METADATA
PROCESSING "LABEL_NO_CLIP=ON" at layer level
Partials=true with labels
