[mapserver-users] Possible tile_map_edge_buffer issue

[forums]

I was just about to post this EXACT same issue.  I have discovered
something else though.  I can force a feature and git to show up where
the other missing data is.  It shows up on tile=0+1+2  Also If I view
the map as mode=map, it works fine, I see my YellowDot and my actual
data from my data source.

LAYER
        NAME "YellowDot"
        STATUS DEFAULT
        TYPE POINT
        FEATURE POINTS -100 20 END END
        CLASS
            STYLE
                SYMBOL "circle"
                SIZE 30
                COLOR 255 255 0
                OUTLINECOLOR 255 0 0
            END
        END
END
