I'm testing autonomous navigation on a Robotnik Summit X mobile robot.

Currently, the navigation stack is tuned well enough to incorporate smooth movements through narrow passages. Dynamic obstacle avoidance when the robot is navigating works fairly well too.

When a a dynamic obstacle(ex: a person) walks in front of it when its navigating, then the robot plans a new path and traverses the newly planned path around the obstacle if there is enough space for it to move (i.e. dynamic path planning).

The catch is when the space is narrow but still nearly wide enough for the robot to fit, it either starts executing a recovery behavior(which I have enabled), or stops without computing a path new path.
Global planner: NavfnROS
Local planner: Trajectory Planner.

I have tried different combinations of goal tolerance parameters for the local planner, but it turns out to be futile. Are there any other attributes of the global/local planner at play that might influence the outcome to not only plan a path in narrow region but also make the robot move in the region after avoiding the obstacle?

Robot: Differential drive
OS: Ubuntu 14.04 LTS
ROS: Indigo.

Thank you.

For reference.
