[mapserver-users] LABEL_NO_CLIP seems not working in mapserver 5.4.1

[Rodriguez, Heraldo]

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
		METADATA

		END
    		IMAGEPATH "/tmp/mapserver/"
			IMAGEURL "/mapserver/"
  
END

Any help would be appreciated. Thanks in advance
