Hey Steve,
I found what the problem was. It was a silly mistake I made.
Some time ago the labels were separated from the polygon in
another layer ( the labelling was no good so we provided the centroids to draw
the labels) Since they were points ,in that case partials=False was fine.
I changed partials to true and that solved my problem. I hope this
comment can help someone if they face the same problem I do.
To sum up
I use "labelcache_map_edge_buffer" "-10" at map level
PROCESSING "LABEL_NO_CLIP=ON" at layer level
Partials=true with labels
Thanks and regards.

Asunto: Re: [mapserver-users] LABEL_NO_CLIP seems not working inmapserver 5.4.1
Hi Rodriguez: I did a couple of quick tests and it seems like the directive is
working as intended, at least with some government unit boundary data. Any
chance you could put together a small test case? Perhaps converting some
data to shapefile and whipping up a simple mapfile that shows the problem.
Are others experiencing the same issues?

Hi everyone,
We have just upgraded from mapserver 5.2.0 to 5.4.1
Our application use OpenLayers, Tilecache with metatiles on, and
postgis.
The label positioning in polygons has improved a lot but now we are
experiencing label duplication on metatile boundaries.
The layer with the issues is parcelas. We are using
labelcache_map_edge_buffer and LABEL_NO_CLIP=ON .
Has anyone an idea why this is happening? The labels length varies from
2 to 4 characters maximum .
A fragment of our map is the following
WEB
# TEMPLATE "set in index.html"
# MINscale 1000
MAXscaleDENOM 1550000

Any help would be appreciated. Thanks in advance
