I guess it's only the /rosout topics?
Those come from roscore, so all non-core topics are gone.
If others are left, the node might either be still running or the master hasn't realized it's gone properly.
Here,I list my operation:bobliao@bobliao-ro:~$ rosnode list
/audio_play
/rosout
/turtlebot_node
bobliao@bobliao-ro:~$ rosnode kill audio_play
killing /audio_play
killed
bobliao@bobliao-ro:~$ rosnode kill turtlebot_node
killing /turtlebot_node
killed
bobliao@bobliao-ro:~$ rosnode list
/audio_play
/rosout
/turtlebot_node
why i can't kill these nodes?

Have you verified all nodes are gone via
rosnode listafterwards? -- I regularly end up with zombie nodes and their topics, too, and the only way I found to get rid of them is restarting the roscore.How to restart roscore?
Alternatively, you can do a
rosnode cleanup. It will try to ping all nodes that are registered at the core and remove them if they are not running.@Lorenz Great find, assuming it works. But why isn't there any documentation about this subcommand?
