## 9. Error Handling and Fallback

### 9.1 RDMA Error Recovery
```java
public class RdmaErrorHandler {
    public void handleRdmaError(RdmaConnection connection, Exception error) {
        log.warn("RDMA error occurred: {}", error.getMessage());
        
        if (isRecoverableError(error)) {
            // Attempt to recover connection
            try {
                connection.reset();

    val closeAtNanos = System.nanoTime()
    webSocket.close(1000, "goodbye", 500L)
    serverListener.assertClosing(1000, "goodbye")

    // Confirm that the hard cancel occurred after 500 ms.
    clientListener.assertFailure()
    val elapsedUntilFailure = System.nanoTime() - closeAtNanos
