Log file stop printing while Importing european map but no errors appear

Hi guys, I'm new here. I have installed nominatim on a centOS machine with 8 gb ram. I'm trying to import europan map and I follow step by step the wiki guide.

Until yesterday all seems worked, but suddenly, after about 10 days of computation, the log file output is as below:

Stopping table: planet_osm_nodes
Stopping table: planet_osm_rels
Stopped table: planet_osm_nodes in 0s
Building index on table: planet_osm_rels (fastupdate=off)
Stopping table: planet_osm_ways
Building index on table: planet_osm_ways (fastupdate=off)
Stopped table: planet_osm_rels in 710s

And no error appear... The db keep growing (very slowly) and if I launch the command:

select * from pg_stat_activity;

I can see some activity. Even if I launch ps -aux command I can see my import process and other process depends on it. Do you think is everything ok?? The import process going on??

Thanks a lot G
