# Broker Failure

Like the Director, the Broker is a robust application that runs indefinitely. The Broker typically only fails when there is a hardware failure, power outage, or network failure. However, the fault tolerance built into the Drivers guarantees that all Services complete even in the event of failure.

The most likely reason that a Driver disconnects from its Broker is a temporary network outage. Therefore, the Driver does not immediately attempt to log in to another Broker. Instead, the Driver waits a configurable amount of time to reconnect to the Broker to which it was connected. After the configured wait time expires, the Driver attempts to log in to any available Broker. Specify the configured amount of time as `DSBrokerTimeout` in the `driver.properties` file. The property is `BROKER_TIMEOUT` in the API.

After the Driver times out and reconnects to another Broker, all Service instances resubmit any outstanding tasks and continue. Tasks that are already complete are not resubmitted. The Service instances also resubmit all state updates in the order in which they were originally made. From the Service instance point of view, there is no indication of error, such as exceptions or failure, just the absence of any activity during the time in which the Driver is disconnected. That is, all Services run successfully to completion as long as eventually a suitable Broker is brought online.

If an Engine is disconnected from its Broker and there are no Failover Brokers, the process shuts down, restarts, and logs in to any suitable Broker. Any work is discarded. Failover brokers are described in the next section.
