The previous fix only addressed ForwardingHandler classes but missed the critical setupDirectConnection() method in route-connection-handler.ts where SmartProxy actually handles connections. This caused active connections to rise indefinitely on ECONNREFUSED errors.
Changes:
- Import createSocketWithErrorHandler in route-connection-handler.ts
- Replace net.connect() with createSocketWithErrorHandler() in setupDirectConnection()
- Properly clean up connection records when server connection fails
- Add connectionFailed flag to prevent setup of failed connections
This ensures connection records are cleaned up immediately when backend connections fail, preventing memory leaks.
