Hi @sandeepdutta ,
Could you please identify which launch file you're using? This will help us identify which nodes are running in that component container and isolate where that spurious error message is coming from.
Here is the launch file .. I am using a realsense camera .

Are there any other launch files that are being launched besides isaac_ros_visual_slam? Which camera are you using? Error X is not from Isaac ROS packages.
Hello Swapnesh, This particular terminal is running only the visual slam node, with the launch file I provided. The camera is launched from a separate launch file on another terminal. If you see the ERROR & WARNING are coming from the same "[component_container-1]" . I get the error occasionally and it does not seem to effect the performance or quality.
Thank you Sandeep
Hello ,
I have started getting these error messages , could you please let me know what I can do to avoid these. The slam continues to work, it is able to recover from this error.
