I have the next issue in AutoModelCar version 2:
All image messages including /rgb /ir and /depth topics stop to publishing after some time working, however, the realsense camera is still on. Other topics as /scan keep publishing messages correctly.
By other hand the timestamp of published images is not changing in time and the header.stamp value is the same for topics like /app/camera/rgb/image_color and /image_raw.
Regards.
