[OSM-dev] render_list coordinates

[Jason Clark]

So I tested this today and when I use the following command to render_list
it starts and then just sits there, no activity on the box

Command (trying to generate ontario/quebec at zoom 8)

/usr/bin/render_list -v -n 4 -all --socket=/var/run/renderd/renderd.sock
--min-zoom=8 --max-zoom=8 -x 8 -X 9 -y 10 -Y 11

Output from render_list

$ /usr/bin/render_list -v -n 4 -all --socket=/var/run/renderd/renderd.sock
--min-zoom=8 --max-zoom=8 -x 8 -X 9 -y 10 -Y 11
Rendering client
