This is can be due to the fact that a label will be printed on a maptile and the polygon or line is on both maptiles. The mapserver will adjust the placement of your label to fit on your tile due to your "partials = false" and position = auto
Setting openlayers in untiled, or using tilecache with metatiles, will solve your problem.

When called using Openlayers, Mapserver renders two LabelItems when the layer to be labels is of type "polygon". I've sort of fixed this issue by including PROCESSING "LABEL_NO_CLIP=1" in the Layer definition. So, for the most part, it works OK. But on some generated maps, I still see one Layer that still renders two Labels. I then noticed that if I tweaked the OpenLayers "minScale" value when defining a new map (see below), I could get suppression of the second label. var map = new OpenLayers.Map( 'map', {controls: [], maxExtent: bounds, restrictedExtent: bounds, projection:"none", minScale: 10000, units: "m" } ); // change the minScale to 15 to suppress the 2nd label I would like to remove the minScale variable from the Openlayers map definition, but that pesky second LabelItem keeps coming back. Has anyone seen/fixed this problem? Should I create a bug ticket. FYI - I am cross-posting to the OpenLayers listserve to see if anyone there has experienced this problem. Here is my Layer definition I've been working with: LAYER NAME CR01 STATUS OFF DATA cr.shp TYPE POLYGON CLASSITEM "FIPS_ADMIN" LABELITEM "ADMIN_NAME" PROCESSING "LABEL_NO_CLIP=1" CLASS NAME "FIPS_ADMIN" EXPRESSION "CR01" COLOR 226 166 166 # E2A6A6 OUTLINECOLOR 32 32 32 LABEL COLOR 0 0 0 TYPE TRUETYPE FONT verdana SIZE 10 ANTIALIAS TRUE POSITION AUTO PARTIALS FALSE MINDISTANCE 300 BUFFER 4 END # end of label END END Thanks!
