### 8.2 Integration Tests
```java
@Test

 *
 * The circuit breaker has three states:
 * - CLOSED: Normal operation, requests pass through
 * - OPEN: Service is failing, requests are blocked
 * - HALF_OPEN: Testing if service has recovered
 */
public class SmbCircuitBreaker {

    private static final Logger log = LoggerFactory.getLogger(SmbCircuitBreaker.class);

    /**
     * Circuit breaker states
     */
    public enum State {

            } catch (Exception e) {
                log.error("Failed to recover RDMA connection", e);
                fallbackToTcp(connection);
            }
        } else {
            // Non-recoverable error, fall back to TCP
            fallbackToTcp(connection);
        }
    }
    
    private boolean isRecoverableError(Exception error) {

        // Increase heartbeat frequency
        // Consider fallback mechanisms
    }
    
    public void handlePartitionRecovery() {
        log.info("Network partition recovered - resuming normal witness operations");
        
        // Restore normal operation parameters
        // Verify all registrations are still valid
    }
}
```

## 9. Performance and Optimization

                failoverStates.remove(channel.getChannelId());
                
                log.info("Successfully recovered channel {}", channel.getChannelId());
                
            } catch (Exception e) {
                log.warn("Failed to recover channel {}: {}", 
                    channel.getChannelId(), e.getMessage());
                
                // Schedule next retry or remove

            }

            recentAttempts.incrementAndGet();
            lastAttempt = now;
        }

        void recordSuccess() {
            // Reduce counter on success to allow recovery
            recentAttempts.updateAndGet(val -> Math.max(0, val - 1));
        }

        void reset() {
            recentAttempts.set(0);
            blocked.set(false);
            blockExpiry = null;
