Hi! I've been using turtlebot software and things are generally working well for me, but I get a recurring warning often when I am running programs. The warning is about a Walltimer that is destroyed immediately after creation. I have not seen this warning in the tutorials I have been reading. Also, I wonder why there is often a lot more text generated on my screen and the process seems to restart several times before working. The output is below:


turtlebot@turtlebot-laptop:~$ roslaunch turtlebot_bringup kinect.launch

... logging to /home/turtlebot/.ros/log/96cb21b2-ce78-11e0-89ae-485d607f80f5/roslaunch-turtlebot-laptop-616.log

I get the Walltimer message too, it seems to be a known issue. AFAICT it's benign, and probably not related to the other issues you're having (which from your description are not very clear -- I think you need to elaborate more on the restarting).
