Compressed image stops publishing after a few seconds

I running ros2 galactic and I have an issue where I try to view a compressed image stream in rqtimageview and rviz on a remote machine. The image will stream for a few seconds and then stop. After that all image topics on the remote machine disappear. I can still echo them on the source machine. I need to restart the ros daemon in order to get the image back. I see no error messages anywhere. Is this a bug with ros2 or image transport?

This issue seems to be worthy mentioning in the GitHub issues (rclcpp/rclpy)

Is this the fault of rclcpp, image_transport library, or something deeper? I'm not familiar with all the infrastructure components of ROS2

I think your issue will be moved to the correct repository if it will be not rclcpp :) I would start there
