[ros-users] ar_track_alvar process has died

Hi everybody,


I'm trying to use ar_track_alvar with uvc_camera.
I launch the corresponding node on my robot, and as soon as it detects a tag, it died. And I don't have any log, just a stacktrace saying "[ar_track_alvar-1] process has died [pid..., exit code -6, ...]"
Do you have an idea on the origin of the problem ?
Thanks a lot
