osrm-routed not returning proper result

Hi,

I installed OSRM back-end on my ubuntu server. I downloaded france-latest.osm.pbf from GEOFABRIK and I filtered/extracted/contracted it to generate a file containing main highways as follows:

./osmconvert france-latest.osm.pbf -o=france-latest.o5m

./osmfilter france-latest.o5m --keep="highway=motorway =motorway_link =trunk =trunk_link =primary =primary_link =secondary =secondary_link" -o=france.mtps.osm

./osrm-extract -p profile.lua france.mtps.osm

./osrm-contract france.mtps.osrm

And finally I started the back-end osrm-routed as follows:

./osrm-routed ../osrm_files_france.mtps/france.mtps.osrm

The backend starts and responds but sometimes it return results that are different from what I would expect or from what the demo server at router.project-osrm.org returns. Here is an example where I want to get the distance between 2 GPS coordinates located on a motorway. The correct distance is 15.1 km, which is consistent with the distance returned by the demo server (15087.7 meters). However my server returns a different route with a distance of 17488.1 meters. I do not understand why I get a different route which makes little sense since the 2 points are located on a motorway same lane. Can anyone help ?

Find below the output returned by both my server and the demo server.
