Hi,
You can put "labelcache_map_edge_buffer" "-10" in the WEB block
metadata. This will ensure that no labels are drawn within 10 pixels of
a tile boundary (you can change the value to increase or decrease the
buffer zone)
E.g.:
MAP
...
WEB
METADATA
"labelcache_map_edge_buffer" "-10"
END
...
END
...
END

OL gutter helps with symbols but breaks labels. PARTIALS false doesn't help
in this case. I didn't find solution how to avoid breaking labels while
using gutter. I suppose the only one is to turn off gutter (prebuild OL map
clone with no gutter) on scales when symbols are turned off (if symbols are
visible in large scales then labels uses large font size and gutter works
fine with labels).

Wendell,
Look at 'gutter' in OpenLayers. It will allow you to get tiles slightly
larger from your Mapserver WMS to get rid of some of the artifacts:

Hope that helps...

Subject: [mapserver-users] clipping symbols at tile boundary?
(this must be basic, but here goes anyway...)
I'm using Mapserver 5.2 with OpenLayers 2.7. I have a
vector mapserver layer with point objects (shown with circle
symbols) on it. The vector layer referenced via
OpenLayers.Layer.WMS and is tiled.
The circles are displayed in the tile that the center is on,
but not the adjacent tiles. That is, if a circle is near
the edge, part of the circle is chopped off.
Is that what 'BUFFER 10' fixes? What about 'PARTIALS
FALSE'? That seems to be just for labels, but that only
shows the label when it completely lies within the tile.
Do I need to turn off tiling completely?
Thanks,
Wendell
