ROS Moveit! Benchmark Shutting Down at the end

edit

Hello ROS developers!

Ubuntu - 16.04 & ROS Version - Kinetic

I'm working with Manipulator-H and using the Moveit! Benchmarking from this tutorial (I did reverse engineering on the code from tutorial to my arm) and at the end the follows happen:

[ INFO] [1564679246.654082483]: SimpleSetup: Path simplification took 0.000002 seconds and changed from 2 to 2 states

Discussing with a colleague, we think that is normal because the code is doing your work (benchmark) and closing at the end. The database created is working in Planner Arena as well. So I want to know if this is indeed correct or do I have any problem with my analysis.

PS: I installed moveit! using apt-get
