tile server for planet working slow and shows error on high end server

Question

I have configured openstreet tile server for planet on ubuntu 12 on dell r730 with dual e5 xeon processors with 40 core total processor combined and 220GB DDR4 ram on sas hdd working on raid 10. I first did setup for great britain map using osm.pbf file from geofabrick.de. then on successful working I did setup for planet.osm.pbf file.

Now after installing tile server for planet when I open http://192.168.1.2/osm/slippymap.html it shows map as ok but on zooming some places shows white tiles at certain level like when I zoom map for united states half of the united states displays white tile and after zooming further it shows some area maps just fine while some shows white tiles and after opening multiple times it displays those areas and for some it does not displays any maps but just white tiles only even after waiting for days.

Please let me know how to resolve this issue.

I build map using this link https://switch2osm.org/serving-tiles/building-a-tile-server-from-packages/

You should likely be pre-rendering the low zoom tiles (0-12 at least) as these take a significant amount of time to render (longer than the timeout of your browser), see the section at the end of the page you linked too.

If I am pre-rendering the low zoom tiles won't that be with the case same apply for other areas which are available can be seen. But this problem is occurring for some areas on at certain zoom level only but not for all

"How fast renderd responds to you" depending on lots of different things, including how many threads you've got already busy rendering tiles and whether there's a queue of stuff to be rendered ahead of what you've just tried to load. It also depends (a lot) on the amount of data in a tile.

The detail on what renderd is doing is usually written to /var/log/syslog - in there you can see (by looking at "START TILE" and "DONE TILE" lines what else it was doing at the time, and where the tile was.

Now I started configuring tile server for planet on a new machine using the same instructions so while I executed the following command :

osm2pgsql --slim -C 32000 --number-processes 4 /home/osm/planet-latest.osm.pbf

Now while osm2pgsql is processing it gave following error and is still continuing to process further as:

Processing: Node(3571919k 181.5k/s) Way(373048k 9.58k/s) Relation(166890 6.83/s) Standard exception processing way_id 255785: topologyException:side location conflict at 2.13239e+06 6.90709e+06 Processing: Node(3571919k 181.5k/s) Way(373048k 9.58k/s) Relation(1485570 11.86/s) Standard exception processing way_id 2563291: topologyException:side location conflict at 2.0772e+06 5.55411e+06 Processing: Node(3571919k 181.5k/s) Way(373048k 9.58k/s) Relation(3404650 15.65/s)

So are these errors fine while configuring a new tile server for planet?
