Question about an error I met when using pointcloud data collected by velodyne 32 channel lidar

[Ruih11]

Hi,
Thank you for your great work!
When I used the Ouster 64 channel lidar as input, the project worked perfectly.
But as I changed the input to point cloud data collected by Velodyne 32-channel lidar, The program ran for a few seconds and crashed.
Error info is like the process has died, exit code -11.
BTW, the point cloud data from two types of lidar are two topics in the same rosbag, as I changed the topic, the program crashed.
Could you give me some advice about this?

Hi, @Ruih11 !

Can you provide a sample of the rosbag?

Hi @csaplaci @horverno !
After rebooting, the problem never reappears. I think it has been fixed.

Hello, first of all thank you for sharing your work.

What could be the reason for this freezing in Rviz? (rviz: fixed frame: velodyne / base_link)

I did not encounter any problems when I ran it on the rosbag record you provided.

Could it be that it is giving an error when it cannot find a road or curb?

Hi @enginksz my guess would be to check your lidar data it may contains some NaN data or similar
