[Geomoose-users] strange highlight-PSOD problem

After much scrutiny and several times down the wrong path, I found that the problems were in the shapfiles of the orthophoto indices.  So I meticulously looked at what was different between a good index layer and one which set off the pink screen.  Projection?  Nope, those were good.  Spatial index?  Nope, no issue there.  It turns out that every index layer with a problem had an attribute called "group".  This item isn't needed by the viewer, and by dropping the "group" item from each index shapefile, the viewer works correctly.

I selected some Augusta/Manchester imagery and got the pink screen then (in firefox: tools-->page info-->Media) went to the url of the pink tile, http://mapserver.maine.gov/cgi-bin/mapserv.exe?service=WMS&version=1.1.1&request=GetMap&styles=&format=image%2Fjpeg&LAYERS=highlight&TRANSPARENT=true&MAP=%2Fms4w_304%2Ftmp%2Fms_tmp%2F%2Fselect_68441350325488.map&FORMAT=image%2Fpng&SRS=EPSG%3A26919&BBOX=374887.49149445,4873840.1331571,516143.11974579,4960061.1010507&WIDTH=924&HEIGHT=564
which offered to download mapserv.exe which I saved then opened with a test editor to see:

<?xml version='1.0' encoding="ISO-8859-1" standalone="no" ?> <!DOCTYPE ServiceExceptionReport SYSTEM "http://schemas.opengis.net/wms/1.1.1/exception_1_1_1.dtd">
<ServiceExceptionReport version="1.1.1"> <ServiceException>
msDrawMap(): Image handling error. Failed to draw layer named 'selected'.
msOGRFileOpen(): OGR error. GetLayer(features) failed for OGR connection `/ms4w_304/tmp/ms_tmp//select_68441350325488.db'.
</ServiceException>
</ServiceExceptionReport>

This is often how MapServer wms errors are delivered.
