Take a look at this boundary where a forest and national park meet:<br>
<br>
<a href="http://osm.org/go/TwUljNo--" target="_blank">http://osm.org/go/TwUljNo--</a><br>
<br>
Notice that the boundaries don't line up. This is because the national<br>
park is in slightly the wrong place. The national park is this changeset<br>
uploaded yesterday:<br>
<br>
<a href="http://www.openstreetmap.org/browse/changeset/1980439" target="_blank">http://www.openstreetmap.org/browse/changeset/1980439</a><br>
<br>
Today I moved the national park into the correct position. The changeset<br>
was closed at 31 Jul 00:09:<br>
<br>

<br>
I then marked the tile you are looking at as dirty. It was apparently<br>
rendered by Mapnik on 31 Jul 03:21:<br>
<br>

<br>
As you can see the data from my new changeset has not been used.<br>
<br>
On 31 Jul 01:33 I added a new changeset with some trails:<br>
<br>
<a href="http://www.openstreetmap.org/browse/changeset/1990063" target="_blank">http://www.openstreetmap.org/browse/changeset/1990063</a><br>
<br>
This was rendered with trails at 31 Jul 03:13:<br>
<br>
<a href="http://a.tile.openstreetmap.org/13/1567/3318.png/status" target="_blank">http://a.tile.openstreetmap.org/13/1567/3318.png/status</a><br>
<br>
If data I uploaded at 01:33 was rendered at 3:13, how come data I<br>
uploaded at 00:09 has not been rendered at the time of writing this?<br>
(03:21)?<br>
<br>
One clue might be that the trails are new data but the movement of nodes<br>
was not. Also JOSM gave me an error of "unexpected end of file" when the<br>
changeset was closing, but the changeset is listed in my edits as being<br>
closed anyway. It also has all 23573 nodes.<br>
<br>
I have cleared my browser cache and tried two browsers.<br>
<br>
I have two other examples of different data/changesets that I just<br>
cannot get Mapnik to render it. In both cases some of the data is<br>
rendered. One of those I've asked for help on here and the Mapnik list<br>
with no solution. I've tried everything I can think of.<br>
<br>
I don't know what the Osmarender update speed is or how to mark tiles as<br>
dirty or find out when they were rendered, so I am unsure if Osmarender<br>
tiles can be directly compared.<br>
<br>
Any help is greatly appreciated, otherwise I am losing confidence.<br>

<br></blockquote></div><br>If the boundary is a relation, that may be the reason. (Since you said it has 23573 nodes, then it must be a boundary relation.) AFAIK, Mapnik (or more properly, osm2pgsql) currently doesn't process relations for diffs. You'll have to wait until the planet reload after next Wed to see the border update.<br>
