<p>The renderd log looks fine after a service restart. Looking at
the pgsql log, I see that pretty much all of the queries end with
a "could not send data to client: Broken pipe". To me, that looks
like renderd is timing out and killing the connection between
itself and pgsql.<br>

Hi Stephen,<br>
<br>
if tiles don't render it could be a problem between renderd and
the postgres db.<br>
<br>
I would advise to restart renderd and look into syslog (grep
renderd) before trying to render. If you see sth. like: "map
failed to load", the reason could be db or file permissions, db
names, missing shapefiles by openstreetmap-carto not applied to
the db or even a missing mapnik xml file (or access
permissions).<br>
<br>
Also check the postgres log.<br>
<br>
Also remember that low zooms are really slow in rendering (use
render_list for those zoom <7).<br>
<br>
What's the size of your db on what kind of filesystem? My last
planet import had been more than 650gb on ext4.<br>
<br>
Cheers,<br>
<br>

My tile server is not rendering tiles. I had it working with
Canada(imported w/o a flat file), but after dropping the
database and re-importing the whole planet(with a flat file)
it no longer works.<br>
<br>
The command I used to import was: osm2pgsql -d gis --create
--slim -G --hstore --tag-transform-script
~/src/openstreetmap-carto/openstreetmap-carto.lua --flat-nodes
~/data/flatnodes.bin -C 6000 --drop --number-processes 8 -S
~/src/openstreetmap-carto/openstreetmap-carto.style
/home/stephen/planet-latest.osm.pbf<br>
<br>
When requesting a tile, this shows up in the log file:<br>
<br>
Apr 23 18:37:15 osm-tilemap renderd[1488]: DEBUG: Connection

Apr 23 18:39:21 osm-tilemap renderd[1488]: DEBUG: Got incoming

Apr 23 18:39:51 osm-tilemap renderd[1488]: DEBUG: Connection

<br>
After 30 seconds it times out. No tiles appear in the cache
directory, even after several minutes. The CPU reaches 20% per
core for all cores, and disk usage is around 200MB/s read.
Both the CPU and disk are used by the postgresql process.<br>
<br>
I am using apache2, mod_tile, mapnik, and renderd.<br>
<br>
Thanks,<br>
<br>
Stephen<br>
