Hello List,
We've been using mapcache_seed ( mapcache SVN checkout 13002 ) to build our
caches mostly successfully so far, but recently have come up against an error
which has only cropped up with a certain layer which includes our text & labels

The next step will be to checkout the latest SVN version. But we are currently
mid-build with some other layers, so are waiting for them to finish before we
do that. But thought we'd fire it out to the list to see if anyone has any
ideas as to what might be causing this?
Below is the mapcache config:
<source name="src_text_update" type="wms">
<http>
<url>http://server/cgi-bin/mapserv601?</url>
</http>
<getmap>
<params>
<FORMAT>image/png</FORMAT>
<LAYERS>text</LAYERS>
<MAP>/opt/mapserver/mapfiles/m6scenz_topo_new.map</MAP>
<TRANSPARENT>true</TRANSPARENT>
</params>
</getmap>
</source>
<tileset name="2012-02-02_text_cache_nztm">
<source>src_text_update</source>
<cache>disk</cache>
<format>PNG</format>
<grid>portalgridnztm1</grid>
<metatile>5 5</metatile>
<metabuffer>10</metabuffer>
</tileset>
"labelcache_map_edge_buffer" "-10" is set in mapserver
WEB METADATA
Cheers
