Hi List,
Today I've been just panning around, zooming and querying (WMS
getFeatureInfo) my small project. A couple of times now I've had the
application fail to successfully retrieve a layer after I've added. There
are only about 5 WMS and one WMS-C layers I'm triggering in the project,
and they all work just fine most of the time, but oddly today I've had it
fail on two different WMS layers when they've been added, albeit at
different times. Layers that have otherwise always been just fine.
In the GeoServer logs I have this:
2013-03-14 10:55:12,677 INFO [org.geoserver.wms] -

The request.log contains this:
"GET
/geoserver/wms?version=1.3.0&TRANSPARENT=TRUE&SERVICE=WMS&REQUEST=GetLegendGraphic&EXCEPTIONS=application%2Fvnd.ogc.se_xml&LAYER=Test_DB%3AEA_RIVER_NETWORK_WSHIRE&FORMAT=image%2Fpng&SCALE=299999.9999054243
HTTP/1.1" 200 259
Does anyone know what does this means or what might be inducing it? It
doesn't seem to be easily replicable (I can't get it to happen again) and I
don't have enough information to know if it is a bug let alone to create a
decent bug report.
Cheers,
Jonathan
