i have an in house parallel delta robot im controller with the joint_trajectory_controller.

I wrote an action client with a action done callback registered to know when the trajectory has terminated. Unfortunately, every trajectory i execute is returning error_code: -5 (GOAL_TOLERANCE_VIOLATED),

To be sure, i tried setting the goal tolerances for the action AND the joints to a exteremely high number (5000000.0), thinking that there is no way it would fail.. but it does, each time.

What can possibly be the cause of this ?

Not an answer, but: this is the only place where GOAL_TOLERANCE_VIOLATED occurs in the ..

.. sources of joint_trajectory_controller. I don't know why it fails for you, but I would check what happens / is that state of your system when the code reaches that point.

Also: you might want to include some examples of goals that you're sending the controller.

Right now your question is rather vague (in the details I mean).
