Hello,
I want to run a node of ROS. When I tape the commande :
rosrun ratslam_ros ratslam_Youness src/ratslam_ros/config/config_irataus.txt.in
The node stops working. And in the log file I get the error :
[ WARN] [1486130761.721137111]: Reason given for shutdown: [new node registered with same name]
But the program still working What should I do?
The error tells you exactly what the problem is
new node registered with same name
This means that you already have another instance of that same node running. When you start another instance the names collide and ROS Master kills the node you're trying to run. If you want to use this node twice, consider using a launch file and giving each instance a unique name.
To add to what jayess said, if you don't think another instance of that node should be running make sure you shut it down somehow (either closing your terminal windows and opening a new one, or use the task manager).
If for some reason you purposely want two versions of the same node running, you can start the second one with a unique name from the command line like this:
rosrun ratslam_ros ratslam_Youness src/ratslam_ros/config/config_irataus.txt.in __name:=my_unique_name
