Hi all:

      I am new to ROS and still going through the tutorial, when I used rxconsole and rxloggerlevel and did not close them until after I launched the "mimic turtles", I used Ctrl C to end them respectively, but when I turn to rxgraph window to see available node graph, they are still there with error "Cannot communicate with ...". I tried rosnode kill and it displayed "killed", but when using rosnode list to see present nodes, they are still there, so does the rxgraph windows shows.

      So I am asking whether this is normal that they cannot be killed, and this won't cause anything unexpected ?

      Thanks for any help.
