explores for a while, and then exploration is stopped, finding no frontiers

[altineller]

Hello,

What parameter must we change to avoid no frontiers found and exploration stopping abruptly? If I move the robot a bit with joystick and then 'ros2 topic pub -1 /explore/resume std_msgs/msg/Bool "{data: True}"' exploration resumes for a little while, and then stops.

I have tried to decrease the min_frontier_size but it did not solve the problem.

Best Regards,
Can
