Over the past month, the server has been busy
trying to re-render all of
the tiles to try to ensure more up-to date maps. This process is more or
less complete now and all of the map tiles should then be at least from
the 1st of December 2011.
While it does not matter much, here's a still old one:
http://a.www.toolserver.org/tiles/parking-bw/17/69173/44572.png/status
So I hope it's just not finished yet, but not broken :-)
A bit of both I think... ;-). It seems it is less finished than I
originally thought. It is now already on the third pass through with
render_old, which should render all of the old tiles.
However, Tirex still needs to be regularly restarted due to memory
leaks, and in the past to tweak some settings. In the time it needs to
restart, the requests get dropped.
There also still seem to be occasionally issues with socket errors, such
that some requests again get dropped.
By the looks more tiles got missed on the first and second pass than I
had expected, so we'll see how long the third pass still takes.
As one month old tiles is still not overly
satisfying, I am now trying
to re-activate diff based tile expiry again.
Off-topic question: is space also a rare resource? I.e. is it needed to
delete old tiles (e.g. ones that have been rendered once but are never
requested again since)?
Yes, space is an issue.
The tiles are on a large 5Tb NFS array that is shared between all
toolserver users. Exactly how much can be used for osm tiles is a little
flexible I guess, but of cause one needs to be considerate with other
users and in total only about 150Gb of space was left. Therefore DaB has
started to delete old tiles yesterday to free up some space. (
https://jira.toolserver.org/browse/MNT-1168 )
I let a du run a couple of days ago (before the deleting of old tiles)
and the result was the following:

31G /tiles/osm-no-labels

Please excuse my ignorance, but what is "default"? Is it the same as
"osm"?
Yes, that is the name of the "default" mapnik style used on
osm.org. It
is just called default for legacy reasons really.

Cheers,
