Sorry for kicking in in english.
While rendering finland.map for openandromaps.org i noticed that rendering times increased from month to month.
Actually Finland map takes 5 days!! to render (12 hours would be standard)
So I searched for monster-relations and found a lot - not uncommon for a country with so much lakes.
However there is a big relation:
With THREE active copies:
So I would kindly ask you to chose which realtion out of these 4 ist the right one and delete the others.
In general such big relations are a performance problem, not only for me but also for all tileservers, and all other tools.
While checking these 4 relations in Josm the main OSM-Server crashed.
I kindly ask mappers to divide such big relations into smaller ones - thanks.
