## Troubleshooting

### Common Issues

#### Connection Timeouts
```java
// Increase timeout values
client.setConnectionTimeout(60000);  // 60 seconds
client.setSocketTimeout(120000);     // 120 seconds
```

#### Memory Issues
```java
// Reduce concurrent threads and batch sizes
crawler.crawlerContext.setNumOfThread(5);

        long now = System.currentTimeMillis();
        long windowStart = currentWindowStart.get();

        // Check if we need to reset the window (1 minute window)
        if (now - windowStart > 60000) {
            currentWindowStart.compareAndSet(windowStart, now);
            globalAttemptsInCurrentWindow.set(0);
        }

        int attempts = globalAttemptsInCurrentWindow.incrementAndGet();
