They do once you restart the server. Unsure what the "phase 3 monitoring" shows where the goroutines go down gradually. If you have new code to deploy you must recompile and therefore restart and those goroutines are gone anyway.
This feels like an AI made-up story but I'm not sure I understand the point of making this up.
However, goroutine leak is interesting! I hope what I learned from this post isn't hallucination.
For example, how could the subscriber send messages/heartbeats to the closed goroutine without an error...
