Hello,
When trying to perform a spatial query (excerpt of code is below), I get after
around 4 minutes an "500 Internal Server Error" in Firebug. The MapGuide
error.log file shows nothing.
I have a layer with around 2500 polygons and a layer with 2500 points (both
SDF, same coordinate system). The goal should be to show the points that have a
specific serial number and are also inside a polygon.
When reducing the number of objects in the polygon layer to around 2100,
everything works fine. It seems MapGuide can't take more polygon objects for a
spatial query. Memory isn't a problem: mgserver.exe is only about 80MB during
the query.
Has anyone got an idea, on how to process more than the 2100 objects?
Regards,
Jan

$featureReader = $layer->SelectFeatures($queryOptions);
$selection->AddFeatures($layer, $featureReader, 0);
$selectionXml = $selection->ToXml();
