After running for a period of time, the ROS 2 node disappears entirely, yet its process is still alive，Why the node be destroyed?

[Kimhlo]

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.

Thanks for the report. Can you please provide the following information/

• Operating system
• ROS distribution (Jazzy, Kilted, etc)
• Transport vendor (zenoh, DDS, etc)

Also, could you provide an example so I can reproduce the issue locally and integrate it into our testsuite? Thanks

@Kimhlo I'm going to close this discussion, I've opened #601 as an issue, the discussions tab is for discussions not for reporting issues. Let's continue there. Thanks.
