> When automaticReconnect=true and the MQTT broker reconnects, if the post-reconnect subscribe() call fails (e.g., broker does not send SUBACK, causing MqttException 32000 after keepAlive timeout), the consumer only logs the error at ERROR level but takes no recovery action. The route remains in Started state while silently consuming no messages (zombie state).
