 - [x] Test cleanup queue edge cases
 - [x] Test memory usage with many unique IPs
 
+### 6. Log Deduplication for High-Volume Scenarios ✓
+- [x] Implement LogDeduplicator utility for batching similar events
+- [x] Add deduplication for connection rejections, terminations, and cleanups
+- [x] Include rejection reasons in IP rejection summaries
+- [x] Provide aggregated summaries with meaningful context
+
 ## Notes
 
 - All connection limiting is now consistent across SmartProxy and HttpProxy
 - Route-level limits provide additional granular control
 - Memory usage is optimized for high-traffic scenarios
