Java 8 为什么Apache Camel route订阅者突然停止接收来自Quarkus发布者应用程序的消息？

问题：

为什么Apache Camel route订阅者突然停止接收来自Quarkus发布者应用程序的消息，尽管Quarkus发布者继续发布消息？ --原因是Quarkus、Camel或Artemis中存在默认配置吗

（Quarkus应用程序发行商通常会继续发送[尽管偶尔会意外地停止发送，没有明显的原因]）

杂项

发布应用程序基于Quark Ampq示例：

可能（只是猜测）发送错误并取消订阅。您能否检查Flowable是否获得

onCancel

回调，并在订阅服务器中捕获

onError

？thx，Justin。我试试看。
