Thank you for your suggestion Andreas,
I have run shp2img and unfortunately:
[r...@terra tmp]# shp2img -o /tmp/out.png -m
/var/www/html/msmap/dynamicmaps/fibUaBrx.map -e "20.259999999999998

Running the command through strace, it ends up like this:

I'm not sure if it faults because it can't read from file handler 4
(Judete.shp), or if it's something else... I also tried by not
specifying Judete in the layer list, but it still dies (while reading
Judete.shp!).
I will look further into problems with AGG (because it renders fine with
PNG)
Thank you for your help - now I know where to look.
Regards,
Adrian
P.S. Ideas are welcome!

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?
Try to bypass the webserver/CGI stuff and launch shp2img directly from
the shell, that should hopefully yield some better output:
shp2img -o test.png -m mapfile.map
If you haven't already done so in your mapfile, you might need to add
an image size (-s 500 500) and/or an extent (-e minx miny maxx maxy)
to the above command line options.
Best regards,
