[Tile-serving] High renderd memory consumption ?

[Kai Krueger]

Hi,

no this is not a known issue and it also doesn't sound like an intended 
feature. Rather it sounds very much like a memory leak.

I am currently trying to track the leak down in order to fix it.

Do you have a rough indication of the time when the leak started? (You 
said you had another server with a more recent renderd. From when is that?)
