QuantumLeap has CrateDB a backend database to persists historic context data. If CrateDB exits immediately with a max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144] error, this can be fixed by running the sudo sysctl -w vm.max_map_count=262144 command on the host machine. For further information look within the CrateDB documentation and Docker troubleshooting guide

sudo sysctl -w vm.max_map_count=262144
