ssl - wso2 das 3.0.1 与 am 1.10.0 : Cannot borrow client for ssl://localhost:7711

Question

我尝试设置偏移量 3 和 0，目前使用 REST 设置的统计数据都可以正常工作。但是，DAS wso2carbon.log 不断抛出以下错误消息:

我想知道是什么原因造成的，如何解决？

Answer 1

我所做的是从 apim admin-dashabord/Analytics 中的数据接收器配置中删除端口 7711。现在只列出 tcp://localhost:7611 。这似乎解决了它，但不知道为什么它在 7711 没有响应，因为它实际上是在 DAS conf/data-bridge/data-bridge-config.xml 中配置的。
