Hi All, I have a Postgresql -> Mapnik - > Tirex -> Mod_Tile - > OpenLayers tile rendering chain set up, but unfortunately I'm having an issue somewhere along the line that I can't solve without help.
As I am using tirex I ran a batch render from 0 down to zoom 12 to try and take some of the initial load off the server once it goes live. Once it had finished I did a quick pan round the map starting in London and I found the issue you can see below in my first screen shot. This section of map refuses to render. It is a rectangle with its left edge running along GMT down to the south of France and to the north of Scotland. Unfortunately though I cannot find it's right edge because as soon as any tile in this section is requested a block appears to happen for a good two minutes or so somewhere along the rendering chain forcing it to hang. Mod_tile doesn't serve any tiles, even at other zoom levels, and it doesn't send any new rendering requests to tirex. In my second screen shot you can see the two tiles that get requested just before the freeze. I can consistently make this happen and resolve the hang by restarting Tirex, which would suggest the problem is there, however looking through all the logs I don't see anything related to this issue. When I ran osm2pgsql on my database server I did receive a few TopologyExceptions, however the process ran though fine and the rest of the map appears to render. I have attached the output from osm2pgsql for you to look at. I'd really appreciate any help. It may be that I'm just being silly, so please let me know if I am!
