----------------------------------
Summary: camel-paho-mqtt5 - Consumer silently stops receiving
messages after broker reconnect when resubscribe fails
Key: CAMEL-24511
URL: https://issues.apache.org/jira/browse/CAMEL-24511
Project: Camel
Issue Type: Bug
Components: camel-paho-mqtt5
Reporter: Jinyu Chen
Assignee: Jinyu Chen
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).
