Peter, yes, I think you’ve put the finger on the problem: my map has lots of small ways that are not connected to the rest of the graph. So I think it actually finds an edge to start off with, but then it can’t find a route because it’s an island, although not a « oneway island », just an isolated island. So is the config prepare.minOnewayNetworkSize although useful in this case ?
In the SO issue you mention, it says that one should try to « decrease prepare.minNetworkSize », is that correct or do you mean actually « increase » the value ? and then should I recompile and rebuild the graph when I play with this value or can I just restart the server ?
