or using the `BIGCHAINDB_CONFIG_PATH` environment variable, e.g. `BIGHAINDB_CONFIG_PATH=.my_bigchaindb_config bigchaindb start`.

## backlog_reassign_delay
Specifies how long, in seconds, transactions can remain in the backlog before being reassigned. Long-waiting transactions must be reassigned because the assigned node may no longer be responsive. The default duration is 120 seconds.
**Example using environment variables**
```text
export BIGCHAINDB_BACKLOG_REASSIGN_DELAY=30
```
**Default value (from a config file)**
```js
"backlog_reassign_delay": 120
```
