> Camel Paho V3 and V5 consumers only disconnect clients when {{isConnected()}} is true and never force-close internally created clients after failed startup. Repeated connection/subscribe timeouts retain Paho clients, Camel contexts, timer threads, and communication resources until the process reaches OOM. Owned clients should always be force-closed on startup failure and shutdown, while externally supplied clients remain untouched.
