Hi,
Could you clarify which part of your problem has a connection with SLD?

[mapserver-users] Apply style on osm layer using sld
Hi All,
I'm trying style a vector layer containing OSM data (places) using the mapscript style shown below. It works so long as I don't add any styling entry pertaining to labels.
However, adding label styling makes MapServer crash while making WMS calls.
It shows a few points with labeled but shortly thereafter, the mapserver instance crashes. There is no error statement in log file also.
This how my layer looks like in map file :
LAYER
CONNECTION "host=localhost port=5432 user=abc password=asdf123 dbname=abc"
CONNECTIONTYPE POSTGIS
DATA 'geom from "OSM_places" using unique gid using srid=4326'

After removing TEXT ("[name]") from each class it shows all points but with this TEXT ("[name]") in layer mapserver crashes.

I am using Mapserver 7.0.1 running as an fcgi process via nginx.
Any idea on what could be wrong? Is there a way I can get a crash dump to help debug this better?
