Usually that's an indication that update_from_dir or update_database
tried to allocate more main memory than available on the system. On all
production and dev systems we're running with 32GB main memory, which is
sufficient to import a planet. IIRC the French instance only runs with
16GB, which really may be not sufficient after all. Do you have a chance
to assign more memory to this instance?

For an initial import, there's an option to add a --flush-size
parameter, see
http://wiki.openstreetmap.org/wiki/Overpass_API/Installation#Database_population_problem
- although I would use a higher value than --flush-size=1 as it will be
painfully slow otherwise.
