Failed to allocate space for node cache file

Hi,

it's my first time trying to set up a OSM server. I have been following this tutorial:

https://github.com/AnderPijoan/vectorosm (with node why i need to change how the maps are rendered for some specific requirements of my project).

i made everything, except that i installed the osm2pgsql from source why the repository version is too old.

but i get stuck at the importing of the DB, i'm using:

  osm2pgsql -m -s -c  -j -v --cache-strategy dense --flat-nodes tempFileErase -d osm -U osmuser --unlogged  --hstore-add-index --exclude-invalid-polygon -r pbf planet-latest.osm.pbf

but i get:

osm2pgsql SVN version 0.83.0 (64bit id space)

any idea of how i can fix it?
