rendering images from ArcSDE

[Thijs Brentjens]

Hi list,
 
When serving a WMS layer on an ArcSDE database, the map images seem to be 
rendered incorrectly. These kind of corrupt images are only rendered when an 
ArcSDE layer is requested. When setting the formatoption "INTERLACE=OFF", 
the stripes disappear, but the image is still not rendered completely.
 
I've attached three files: one with layers from shapefiles only (interlace 
on), one with an ArcSDE layer (interlace on) and one with an ArcSDE layer 
with interlace off. IE can't display these images (Firefox can).
 
The problem doesn't seem to depend on the image format. It happens both with 
JPEG and PNG images.
 
We're using mapserver 4.4.2, compiled against GDAL 1.2.5 on a linux 
platform.
 
Does anybody have a clue what is happening here?
 
best regards,
Thijs
