Covers SIGTERM/SIGINT handling, why graceful shutdown matters for data integrity, and how to wait for in-flight commands before exiting. Demonstrates a concurrent Go implementation using goroutines, channels, and atomic compare-and-swap to safely transition server state from busy to waiting to shutting down, including a tricky edge case where a server could re-enter busy state after shutdown is initiated. ## Full article daily.dev links to this article rather than hosting it.
