### What "escalating to SIGTERM" mean ?

Hi everyone !

I have develop my on keyboard to start doing a teleoperation, to read the keys I have created a thread and and i have a ros::rate to publish my data in other frequency. But when I kill all the execution ros send this message :

Failed to call commander_service [keyboard-2] escalating to SIGTERM

So I have search for an easy example and I found: http://ros.org/wiki/turtlebot_teleop

I have found the keyboard driver and tried and I received the same message.

http://www.ros.org/doc/api/turtlebot_teleop/html/turtlebot__key_8cpp_source.html

In this code I find a this line : signal(SIGINT,quit);

And I decided to replace the SIGINT with SIGTERM. But I doesn't solve the error, but the function quit is executed.

So do you know why is happening it and how to solve ?
