Hello, I am trying to run the algorithm in my own data. Unfortunately, I am receiving this error after a while of processing the data:

[velodyne_nodelet_manager-2] process has died [pid 28341, exit code -9, cmd /opt/ros/noetic/lib/nodelet/nodelet manager name:=velodyne_nodelet_manager log:=/home/aleksandr/.ros/log/be799298-0cf6-11ed-aca3-c5d0d9103af3/velodyne_nodelet_manager-2.log]. log file: /home/aleksandr/.ros/log/be799298-0cf6-11ed-aca3-c5d0d9103af3/velodyne_nodelet_manager-2*.log

Update: I have partially solved this problem by reducing map resolution. File: hdl_graph_slam_400.launch or any other launch file you are working with. parameter to be changed: <param name="map_cloud_resolution" value="0.25" /> default value is 0.05. try to increase the value if you faced this problem. I still do not understand what causes this problem. My guess is lack of RAM or swap area. My spec is: Intel Core i7 8th Gen, 16Gb RAM, SSD, 8Gb video memory. Good luck!
