[mapserver-users] Premature end of script headers: mapserv

[Rahkonen Jukka]

Hi,

If I understood right "mol" is the name you have given at MAP level.  I do not know if using &layers=mol should really work or not, I have never tried it that way.  I use wms_titles advertised at layer lever, either comma separated list or &layers=all.

Try what happens when using &layers=all.  If it fails add "DEBUG 5" into layer definitions and have a look at ms_errorfile after doing some failing requests.

Hi..

I added the new shapefiles to PostGIS using shp2pgsql etc and it was
successful. After that, in my mapfile, I included a new layer for each of
these shapefiles. What I copy-pasted in my mail was the layer that I added
in my mapfile.

I have included WMS metadata in the beginning of the mapfile:
WEB
    IMAGEURL "/tmp/"
    IMAGEPATH /tmp/ms_tmp/
      METADATA
        "wms_title"     "MOL"  ##required
        "wms_onlineresource" "....."   ##required
        "wms_srs"       "EPSG:2060"  ##recommended
     END

I was getting a good output using WMS request:
http://....../cgi-bin/mapserv?map=/data/..../t....map&SERVICE=WMS&VERSION=1.1.1&REQUEST=getmap&layers=mol&STYLES=&SRS=epsg:2060&FORMAT=image/jpeg&WIDTH=600&HEIGHT=500&BBOX=332271.136,2800048.4565,335043.0915,2803465.287

As I kept adding new layers, I suddenly started getting an Internal server
error on my browser. When I checked the error log, it read: Premature end of
script headers: mapserv.
All the new layers were similar to each other, with only different "NAME"
and "DATA". But the internal server error would just not go unless I reduced
the total number of layers in my mapfile.

shp2img works fine and I get an output. What doesnt work is the WMS. Works
when I reduce the total number of layers in my mapfile. Is there a maximum
number of layers or classes that we can use? I use version 5.0

After reading the latest reply, I added WMS metadata to the "layers" also,
but WMS still doesnt work.

Please help.
Thanku v much..
