After running for a period of time, the ROS 2 node disappears entirely, yet its process is still alive. What could be causing this? In my code, the main thread uses the #[tokio::main] attribute, and within asynchronous subscriptions, I directly spawn related async operations using tokio::spawn.

@Kimhlo can you try with the latest version of rclrs (0.7.0)? A snippet that exhibits this problem would be of great value, thanks.
