Graceful shutdown handlers fail when kill -9 strikes
Original: You write a graceful shutdown handler in Node.js, Python, or Go. You catch SIGTERM and SIGINT , close your database conn
Developers are discussing a common gap in software reliability: applications written in Node.js, Python, or Go often include shutdown handlers that catch SIGTERM and SIGINT, close database connections, flush files, and exit cleanly. But these handlers never run when a process receives SIGINT's harsher cousin, kill -9, or when Kubernetes force-kills a container after a timeout, leaving cleanup unfinished and potentially corrupting state.
Why now: The tradeoff between clean shutdown handling and unavoidable forced termination is a persistent pain point for engineers running services in containerised environments.
Evidence
- You write a graceful shutdown handler in Node.js, Python, or Go. You catch SIGTERM and SIGINT , close your database connections, flush open files, and exit cleanly. Then someone runs kill -9 (or Kubernetes kills your container after a timeout). Your cleanup handlers never run.… · hackaday@www.urbanmind.net · 4
