hi,I am using laser assembler package for 2D pointCloud to 3D point-cloud conversion. First I am start launch file (laser.launch), then followed by I'll run cpp file, when I run .cpp file suddenly the roslaunch(master) file will be shutdown, the error is

[ WARN] [1375768306.726458068]: Shutdown request received.
[ WARN] [1375768306.726502466]: Reason given for shutdown: [new node registered with same name]

launch file is

<launch>
    <node pkg="laser_assembler" type="laser_scan_assembler" output="screen"  name="laser_scan_assembler">
    <remap from="/scan" to="tilt_scan"/>
    <param name="tf_cache_time_secs" type="double" value="11.0" />
    <param name="max_scans" type="int" value="400" />
    <param name="ignore_laser_skew" type="bool" value="true" />
    <param name="fixed_frame" type="string" value="/sr_lidar1_scan" />
  </node>
</launch>

Have you read the [laser_assembler doc](http://ros.org/wiki/laser_assembler#Parameters)? It states the `laser_scan_assembler` requires a parameter fixed_frame.

I was running the same node in two launch files, one in my gazebo world launch file and one in the controller launch file. The gazebo launch file would init the node and the controller launch would kill it. Thank you!
