queryByShape raster kills CGI with greater than 345+ records selected

[Burgholzer,Robert]

I figured out how to fake the queryByFeatures with a queryByShape,
however, my CGI process is crashing when the number of records exceeds
somewhere in the neighborhood of 340.  The error I get is:

 

"CGI / FastCGI has encountered a problem and needs to close..."

 

Using mapserver 4.10.1 on Apache 2.2 in windows XP.

 

I saw a limitation in some previous posts that seemed to suggest a much
higher threshold of failure.  The interesting thing (to me) is that the
script manages to return selected records, and only bombs later on in
the process.  Does anyone have any idea as to how to work around this,
or if there is some setting that I have botched?

 

My code looks like so:

 

   $rastermap = $amap->map->getLayerByName('depart30');

   $shapemap = $amap->map->getLayerByName('selectedsegs');

   print("Result ID: $amap->lastresid <br>");

   $shapemap->open();

   $rastermap->queryByShape($shapemap->getShape(-1,$amap->lastresid));

   #$rastermap->queryByFeatures($shapemap->index);

   $shapemap->close();

   $amap->activelayer = 'depart30';

   $listobject->queryrecords = $amap->getResultArray();

   $listobject->showlist();

   $recs = count($listobject->queryrecords);

   print("$recs Results Retrieved. <br>");

 

As noted, the script executes PAST the record retrieval, prints out the
number of results that have been returned, then bombs.

Or, can I fake it by using a querybyShape??

Is it possible to do a queryByFeatures on a raster?  That is, I want to
select a shape feature, then have that used as a query shape to
summarize info in my overlapping raster.

 

I am trying this:

 

   $rastermap = $amap->map->getLayerByName('depart30');

   $shapemap = $amap->map->getLayerByName('selectedsegs');

   $rastermap->queryByShape($shapemap->index);

 

But cannot seem to retrieve any data (even though the raster is
definitely overlapping).  

 

My raster layer is a geoTiff (also tried as Gif, same result), with a
manually specified world file. The images display overlapping in the map
view window.

 

Any help would be appreciated,

 

r.b.
