[Mapserver-users] NQUERY Internal Server Error

[Düster Horst]

I'm a little bit confused about a query problem I'm faced with. Today I did
the upgrade from MS 3.6.7 to MS 4.0.1. I made all the necessary migration
steps (I hope). NQUERY with the most layers work fine, but one layer
produces an "Internal Server Error". Apache error_log says "Premature End of
Header". After some modifications of the concerned layer I found out a
strange fact. Take a look at the attached Mapfile snippet. 
 
Some layer information:
The underlaying data are stored in a Postgres-7.2.4/PostGIS-0.8.1 DB with
4500 recs. 
The values of the attribute o_art are between 100 and 41500. 
 
with   
DATA "wkb_geometry from (select oid,* from arp_ripl_poly where o_art >= 1000
and o_art < 30412) as foo usinng SRID=-1"
NQUERY works
 
with   
DATA "wkb_geometry from (select oid,* from arp_ripl_poly where o_art >= 1000
and o_art < 30413) as foo usinng SRID=-1"
NQUERY does not work -> Internal Server Error

with   
DATA "wkb_geometry from arp_ripl_poly"
NQUERY does not work -> Internal Server Error

I would be appreciative about any hint.
