# I Fixed a Shutdown Race Condition That Could Leave Bot Processes Running Forever 🐞

This is a submission for *DEV's Summer Bug Smash: Clear the Lineup** powered by Sentry.*

Project Overview

I maintain StayPresent, an open-source Python package that helps developers keep bots and background services running on platforms such as Render, Railway, Koyeb, and Heroku.

The library launches a lightweight web server alongside one or more bot processes, supervises them, and automatically restarts them if they crash. Because it's designed for long-running applications, reliability is far more important than adding new features.

During development of v1.5.10, I found a subtle shutdown race condition that could leave processes running after the application was supposed to exit.
