| `N8N_RUNNERS_MAX_OLD_SPACE_SIZE` | String | | The `--max-old-space-size` option to use for a task runner (in MB). By default, Node.js will set this based on available memory. |
| `N8N_RUNNERS_MAX_CONCURRENCY` | Number | `5` | The number of concurrent tasks a task runner can execute at a time. |
| `N8N_RUNNERS_TASK_TIMEOUT` | Number | `60` | How long (in seconds) a task can take to complete before the task aborts and the runner restarts. Must be greater than 0. |
| `N8N_RUNNERS_HEARTBEAT_INTERVAL` | Number | `30` | How often (in seconds) the runner must send a heartbeat to the broker, else the task aborts and the runner restarts. Must be greater than 0. |
| `N8N_RUNNERS_TASK_TIMEOUT` | Number | `60` | The maximum time, in seconds, a task can run before the runner stops it and restarts. This value must be greater than 0. |
| `N8N_RUNNERS_HEARTBEAT_INTERVAL` | Number | `30` | The interval, in seconds, at which the runner must send a heartbeat to the broker. If the runner doesn't send a heartbeat in time, the task stops and the runner restarts. This value must be greater than 0. |
| `N8N_RUNNERS_INSECURE_MODE` | Boolean | `false` | Whether to disable all security measures in the task runner, for compatibility with modules that rely on insecure JS features. **Discouraged for production use.** |
| `N8N_RUNNERS_TASK_REQUEST_TIMEOUT` | Number | `20` | How long (in seconds) a task request can wait for a runner to become available before timing out. This prevents workflows from hanging indefinitely when no runners are available. Must be greater than 0. |
