PT Berlin Example "Killed"

Hi Guys,

I have followed the steps in the PT example (https://github.com/graphhopper/graphhopper/blob/master/reader-gtfs/README.md) and can’t get it to work with the Berlin/Brandenburg datasets, while other GTFS/PBF combinations work well (Cologne for example). I get the following logs/error messages:

Killed

I suspect some kind of RAM issue, but I’m on a 12 GB machine, which should be sufficient. The command I’m running is
java -Xmx10g -Xms10g -Dgraphhopper.datareader.file=berlin.pbf -Dgraphhopper.gtfs.file=berlin.zip -Dgraphhopper.graph.flag_encoders=pt -Dgraphhopper.prepare.ch.weightings=no -Dgraphhopper.graph.location=./graph-cache -jar web/target/graphhopper-web-*.jar server config.yml

I’ll gladly assist if any further debugging info is needed.
Thanks in advance

Felix
