# Runbook — Celery

## Check

```bash
sudo systemctl status djangoplay-celery
```

## Logs

```bash
sudo journalctl -u djangoplay-celery -n 200 --no-pager
```

## Restart

```bash
sudo systemctl restart djangoplay-celery
```

## If Tasks Stall

Check:

```text
Redis availability
Celery process state
RAM
CPU
database connectivity
task logs
```

On the constrained production VM, avoid increasing concurrency without measuring actual memory headroom.

## Settings

Celery must resolve the same settings module as Django.

The source of truth is:

```text
paystream.settings.bootstrap.resolve_settings_module()
```
