Database using up too much space

[ipg0]

Describe the bug
Nominatim database is expected to be about 900 GB, but while still importing, the database grew to more than 1.5 TB and continues to grow.

To Reproduce
Steps to reproduce the behavior:
Container started with command:

docker run -d -e PBF_PATH=/sources/data.osm.pbf -e REPLICATION_URL=https://planet.openstreetmap.org/replication/day/ -e THREADS=16 -e NOMINATIM_PASSWORD=[redacted] -e IMPORT_STYLE=address -e POSTGRES_SHARED_BUFFERS=4GB -e POSTGRES_MAX_WAL_SIZE=16GB -e POSTGRES_CHECKPOINT_TIMEOUT=30min -v /var/lib/pgsql/geocode-replicated/osm.pbf/:/import/:Z -v /var/lib/pgsql/geocode-replicated/pgsql/:/var/lib/postgresql/14/main/:Z -v /var/lib/pgsql/geocode-replicated/nominatim:/nominatim/:Z -v /var/lib/maps/geocode-sources/:/sources/:Z --shm-size=16g --memory=32g --memory-swap=100g -p 7071:8080 -p 5440:5432 --name nominatim-replicated mediagis/nominatim:4.2

The import process is now at the Starting interpolation lines (location_property_osmline) stage.
The Postgres directory is over 1.5 TB.

Expected behavior
Database size for planet data is expected to be about 900 GB.

Server:

• OS & Version: CentOS 7
• Docker Version: 19.03.13
• Nominatim Version: 4.2.1

Additional context
The problem is I have only allocated 2TB to the Nominatim database volume, including additional files it now only has about 300 GB of free space left.

I think you should add the flatnode file:
-v nominatim-flatnode:/nominatim/flatnode
