Hi all,

I am trying to run the render_list command to render my maps. However I am getting a "rendering failed with command 4, pausing." when it gets to zoom 7. The same "error" will happen for about 20-30 times before it gets to "Rendering All tiles for zoom 7..." and then back to the error. Any help would be greatly appreciate and please let me know if I need to provide more logs or any more details.

Edit: based off the syslog it looks like its going to pull some maps from 7/88/48 (for example) but cant find it?

jth-admin@xxxxxxx:/home/osm$ sudo ./render_world.sh

Here is the contents of render_world.sh (just used for logging):

jth-admin@xxxxxxx:/home/osm$ cat render_world.sh
#!/bin/sh

time render_list -a -s /var/run/renderd/renderd.sock -z 0 -Z 7 --force
echo Finished render for World level 0-7 >> render.log
date >> render.log

echo "Done"

here is a small snippet of /var/log/syslog

Here's your problem:

Dec 19 13:00:48 xxxxxxx renderd[3795]: Received request for map layer 'default' which failed to load

There's something that the map style is trying to do which failed to load. Try restarting renderd and look at syslog, and there will be more information there.

in my case the problem was get-shapefiles.py faild to download some of the files so map layer 'default' dident find the shapes and failed , so i downloaded and added them manually.
