z11 tiles not updating

Description

The tiles of the main (Mapnik) slippy map at zoom 11 aren't updating as fast as the tiles at other zoom levels. Zoom 12 and closer usually gets updated in less than an hour. Zoom 10 and further out is usually updated within a couple of days. Zoom 11, on the other hand, seems to be stuck. All of the z11 tiles in my area seem to have been last rendered on 11 July, and are reported as "clean". Re-requesting the tiles in my browser apparently has no effect. Appending "/dirty" to the URL seems to be the only way to get these tiles to re-render.

I suspect that when a z11 tile is requested, there's a failure in whatever mechanism is supposed to decide whether the tile needs to be re-rendered.

Wow, within a couple minutes of opening this ticket, a huge area of z11 tiles updated all at once!

Yet there are still numerous tiles around which are more than 4 weeks old.

Even if manually marking a few tiles as "dirty" is what it takes to get a large area to re-render, this is still a problem.

Zoom 0 - 11 normally only get re-rendered after a full import which currently happen every few weeks. The auto-refresh mechanism is disabled for 0-11 since these tiles would otherwise get rendered on an almost continuous basis & most normal minor edits are practically invisible at these zoom levels.

I have forced through a re-rendering of all the 0-11 tiles so you should now see tiles less than a couple of days old. I will think about making this a weekly activity regardless of the full planet import.
