mapnik parallel rendering limited to 4 #142

Closed zdila closed 4 years ago

zdila commented 4 years ago

Hello,

We are using pool of mapnik workeds and I have just observed that even if there are 24 workers requested to render then max 4 are doing so and other are waiting. I could see it by observing postgres connections.

Workers are executed from the single process. If we run two separate processes then eah of them uses max 4 db connections (mapnik workers).

Is there somewhere any default limit that can be configured?
