After running this command: roslaunch runtime_manager runtime_manager.launch 
Newly opened terminal can display the following error:
            top: bad delay interval '0.1'
            Exception in thread Thread-8:

Also if above couldn't solve the problem: Add this to ~/.bashrc:

export LANG="en_US.utf8"
export LANGUAGE="en_US.utf8"
export LC_ALL="en_US.utf8"
