WSO2 API 管理器抛出无法将事件发送到端点错误

Question

在我们的部署中（WSO2 API manager 2.0.0 All-in-One 2 node clustered with separate WSO2 DAS server），由于 SVN 存储库已损坏，depsync 出现问题。该问题已解决，但现在我们注意到 wso2carbon.log 中重复出现以下错误。

因此我不确定是否与 SVN 存储库损坏有关，但是这个问题是我们在事件发生后观察到的。

澄清一下，这是指本地 thrift 服务器：

tcp        0      0 0.0.0.0:7611            0.0.0.0:*               LISTEN      1549/java
tcp        0      0 0.0.0.0:7711            0.0.0.0:*               LISTEN      1549/java

或 DAS thrift 服务器？

tcp        0      0 0.0.0.0:7612            0.0.0.0:*               LISTEN      1560/java       
tcp        0      0 0.0.0.0:7712            0.0.0.0:*               LISTEN      1560/java

两者似乎都可用。

这个错误对系统有什么影响？

感谢任何帮助。谢谢

这是数据发布到DAS。检查从 APIM 到 DAS 节点的连接。如果 thrift 绑定 IP 与请求的 IP 不同，就会发生这种情况。

影响是数据没有发布到 DAS。
