[Tilesathome] Requests for no layers

[Ed Loach]

I've had a few of these in the last hour or so (about 8 or 9). Checking now there were three on page 1 of the Unhandled requests page with no layers and a Requested by of "tiledetail page request". Any idea what causes these? I'd request a rerender to get some layers but they'll show as active for 6 hours and then I'll lose track of them. Checking a recent example:
http://tah.openstreetmap.org/Browse/details/tile/12/1999/1277/

--- Start quote ---
Active request at priority 2 has been requested 11 hours, 36 minutes ago.
Renderer: EdLoach, Layers left to render: 

Finished request at priority 2 has been requested 17 hours, 34 minutes ago.
Renderer: aj_osm_aj_gps_net, Layers left to render: 

Finished request at priority 2 has been requested 1 day, 14 hours ago.
Renderer: flohoff, Layers left to render: 

Finished request at priority 2 has been requested 1 day, 14 hours ago.
Renderer: GwennG, Layers left to render: 

--- End quote ---

So it is still an active request (renderer me) even though there are no layers left to render.

No zips to compress or unload (yet) - 933,1819 similarly had no layers with the request.
