Hello everyone,
I would like to create europe-latest.pbf with the following profiles:
bike2, mtb, racingbike, foot, hike
I use the following configuration:
graph.dataaccess: MMAP
I use the elevation profile:
graph.elevation.provider: srtm
I have rented a server with 128 GB Ram from digital ocean.
I have started the process as follows:
export JAVA_OPTS="-Xmx125g -Xms125g"
./graphhopper.sh -a web -i europe.pbf -d
Everything ran through until the last profile and then it didn’t go any further.

About 10 minutes after the last log, the CPU usage and disk i/o went to 0 and stayed that way.
What could be the cause? When the RAM runs full, an error message is actually written in the log.
I’m using the latest release from graphhopper.
Many thanks
