[OSM-talk] Some tiles not rendering?

Hi Nakor.
As far as I know the queue is the whole knowledge about tiles which have 
to be rerendered.
If a tile has to be rerendered due to a changeset, that tile is 
submitted to the queue exactly once, at the time the queue management 
reads that changeset.
If the queue is full at that time, it's in fact not added - and not 
added later, too.

An empty queue at night does not help if there is no call to add your 
tile to the queue.

regards
Peter
