Luigi central scheduler daemon termination blocks task execution

If the luigid daemon process terminates or fails to start, Luigi tasks cannot be scheduled or executed. The scheduler listens on port 8082 by default and must remain running for the duration of task execution.

Before executing Luigi tasks, verify luigid process is running with `ps aux | grep luigid`. Configure process supervision (systemd, supervisor, or container orchestration health checks) to auto-restart the daemon on failure. Monitor port 8082 availability. Keep the terminal running or daemonize the process properly.
