Import crash for Asia

I am running a import separately for Asia pbf file. I have a RAM of 16 GB every time its crashing.
Any suggestions to be done in config my config file attached.
tried with datareader.dataaccess: MMAP and without

Command used

java -Xmx16G -D"dw.graphhopper.datareader.file=asia-latest.osm.pbf" -jar graphhopper*.jar import config.yml


What is the error?

If you’re getting OOM errors or heap space errors, you may need a lot more than you think. I was doing South Korea, a relatively small country, and I needed 14GB.

If you are using the latest version 9.0 please ensure to use the example config as a start and do not omit the car.json custom model.

@karussell got OOM error.
car.json custom model in 9.0 will that help in optimization?

Any rough idea how long will it take to complete for Asia

I tried freeing up space in the machine there is a good progress but its on pause for almost 18hrs with below log.
