I followed the guide to tried the Turtlebot3 navigation with Gazebo simulation, and everything worked fine.

However, when I added the following argument in turtlebot3_navigation/launch/turtlebot3_navigation.launch, some parts seems to be broken.

<node pkg="move_base" type="move_base" respawn="false" name="move_base" output="screen" launch-prefix="valgrind --tool=callgrind" >

The command roslaunch turtlebot3_navigation turtlebot3_navigation.launch map_file:=$HOME/map.yaml get the following info:

... logging to /home/shaohua/.ros/log/ffe180e2-c6a1-11e7-9b70-6045cb61bc51/roslaunch-hua-14980.log

It seems the navigation stack lost some service connection when work with Valgrind.

Can anyone help?

Thanks in advenced for any reply!
