[Tilesathome] server processing of tiles stalled?

[Jon Schlueter]

Yesterday the server was making progress on getting through the
backlog of tiles that had accumulated.  Then Yesterday evening it
seems that the tiles processing halted.  It also seems that it
corresponded to the limit being dropped back to 500, but that may just
be coincidence.  Can someone check and see what the status is?

Thanks
Jon
