A step‑by‑step guide to diagnose uWSGI worker recycling, memory‑related reloads, harakiri timeouts, and graceful‑reload mercy issues using logs, stats, and cgroup limits.

Constraints and uncertainty Graceful reload waits for active requests but does not define a worker shutdown sequence. --lazy-apps
