Delay in JointStates

edit

Hi
I am working on ROS Kinetic with Ubuntu 16.04. I am simulating my robot with gazebo and ros-control however the terminal always shows this warning ::

process[coro/joint_controller_spawner-1]: started with pid [21948]

process[robot_state_publisher-2]: started with pid [21949] Loaded

joint_state_controller Started ['joint_state_controller'] successfully

[coro/joint_controller_spawner-1] process has finished cleanly log file: /home/bhoot/.ros/log/54979f64-835c-11e8-8840-a08cfdeabd87/coro-joint_controller_spawner-1*.log
