I'm sure of the two styles definition, because I want a blue line with a
black border (see
http://www.mapmedia.de/dokumente/umn_signaturen_howto/).
I also removed MAXSCALE, and I can see the entire map (but this appened
also before removing MAXSCALE).
When I zoom to certain portions of the map, I have the internal server
error.
So, I think that the problem is the shapefile, but what tools can I use
for being sure of it?
(BTW, the shapefile is managed by a colleague, who uses ArcView and, for
him, all seems good).

Are you sure of the two styles definition in your layer? Try to remove
your MAXSCALE and load the entire map. If this layer is actually the
problem, you should have an internal server error.

As I told in another message, I can browse the map (and this layer)
until I remain out of certain extents that give me error.

Most of the time, internal server error is caused by a syntax error in
the mapfile. Can you post the Elementi_stradali layer section of your
mapfile?

Hi list,
I use CGI MapServer 4.2.3 on a RH9 with Apache 2.0.50:
<!-- MapServer version 4.2.3 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG
OUTPUT=WBMP OUTPUT=PDF SUPPORTS=FREETYPE INPUT=EPPL7 INPUT=OGR
INPUT=GDAL INPUT=SHAPEFILE -->
All works, but I have a map that returns an "Internal Server Error" when
I try to zoom and show a certain extent with a specific layer.
I think the problem is due to the shapefile (or a part of it), but...
how can I be sure of it?
The browser only show the "Internal Server Error" page.
The Apache error log says: "[Mon Dec 06 07:13:04 2004] [error] [client
172.16.20.4] Premature end of script headers: mapserv"
I compiled MapServer with --enable-debug, set "DEBUG TRUE" in the map
section of the mapfile, and tried to use shp2img with these results:
------------------------------------------------------------------------

Elementi_stradali
Segmentation fault
------------------------------------------------------------------------
----
When shp2img processes the "bad" layer ('Elementi_stradali'), it exits
with a 'Segmentation fault' and without a more explicit error message.
I launched the following command (where "road_elements.shp" is the
probably bad shapefile):
[root at redhat cat_strade]# ogrinfo -al road_elements.shp -spat 2491361
4510665 2492415 451145
It returns a 85 Kb output with apparently no detected errors.
How can I understand where the error lies?
Is there a more powerful debug tool?
Thank you,
Daniele
