Hi,
I made upgradre to 4.9.0
osrm-extract output give following result :

But when i try to make osrm-prepare
/usr/local/bin/osrm-prepare -t 16 -p "/data/osm/osrm-backend/profile.lua" /data/osm/osrm-backend/europe-latest.osrm > europe-prepare.2015.12.31.log

I get only following warining
[warn] The recommended number of threads is 4! This setting may have performance side-effects.
[warn] [exception] osrm input file misses magic number. Check or reprocess the file

I see that europe-latest.osrm.ebg file is empty but I don`t know that is fine or not.
