Hello David,
I got the 500 errors from the http error log file. Unfortunately no
additional information is provided.
I added the MS_ERRORFILE and DEBUG statements to my map file and
although the errorfile is created, I don't get any other information
(neither when the map loads perfectly, nor when it dies with premature
end of script headers.
I read RFC 28 (http://mapserver.org/development/rfc/ms-rfc-28.html) and
they specified that the server should be compiled with
-DENABLE_STDERR_DEBUG, so I recompiled mapserver:
CFLAGS=-DENABLE_STDERR_DEBUG ./configure --with-freetype --with-png
--with-agg=../agg-2.5 --with-proj --with-ogr --with-gdal --with-xml2
--with-wfs --with-wcs --with-wmsclient --with-wfsclient --with-postgis
--with-threads --with-sos --with-mygis --with-geos --with-tiff
I used the new binary and unfortunately nothing changed :(
My (relevant part of the) mapfile looks like this:
MAP
CONFIG "MS_ERRORFILE"
"/tmp/mapserver.log"
CONFIG "MS_DEBUGLEVEL"
"5"
DEBUG 5
...
END
What else can I try?
Regards,

Thank you for your suggestion.
I have corrected the mapfile ( added IMAGETYPE 'AGG'), however, when
I try to load the map, I get a 500 web server error:
[Tue Jun 16 13:43:25 2009] [error] [client 80.97.196.77] Premature
end of script headers: mapserv, referer: http://terra/msmap/testmap.pl
It seems to me that mapserv dies and doesn't output any headers back.
How could I find out the error message?
The first place to check is the web server log. HTTP errors (and 500
is one) are usually visible there. I'm guessing that mapserver has a
problem parsing the map file and you can usually discover the line it
is having a problem with in the web server's log.
The second level of logging is:
CONFIG "MS_ERRORFILE" "path_to_mapserver.log"
which provides more detail, but you usually have to configure DEBUG ON
(or DEBUG 1-5) as well for this to be useful.
Regards,
David
