ERROR: Out of memory for dense node cache

[thedmdim]

Here is my configuration:

docker run -it --rm \
  -e PBF_URL=https://download.geofabrik.de/europe/germany-latest.osm.pbf \
  -e REPLICATION_URL=http://download.openstreetmap.fr/replication/europe/germany/minute/ \
  -p 1003:8080 \
  --name nominatim \
  mediagis/nominatim:3.7

That's what i get:

Well, how much RAM to you have?

Docker for windows only assigns like 1gb to the VM by default.

[thedmdim]

Totally my VPS has 8gb RAM. Everything as usual VPS, ubuntu linux 8gb/200gb

[leonardehrenfried]

That's a bit tight. The default conf assumes you have 32gb of ram. The tuning section in the readme contains info on how to configure nominatim for less memory but if I remember correctly, it doesn't change the --cache param.

[thedmdim]

yes you are right, there is no key to tune --cache, and i dunno how to walk-around this

[leonardehrenfried]

you can add it, build an image locally, test it and send a PR when it works.
