加载注册表资源时WSO2 EI 6.3.0记录错误

Question

我在WSO2 Enterprise Integrator 6.3.0中有一个代理，其端点在conf注册表中配置。有时我在此代理中收到错误，并在LOG中显示消息：

[2018-09-12 09:33:22,542] [-1234] [] [SynapseWorker-11] ERROR {org.apache.synapse.config.xml.endpoints.LoadbalanceEndpointFactory} -  Invalid endpoint configuration.
[2018-09-12 09:33:22,542] [-1234] [] [SynapseWorker-11]  WARN {org.apache.synapse.config.SynapseConfiguration} -  Error while loading the resource conf:services/corp/servicev1/endpoint/ERPEndpoint.xml from the remote registry. Previously cached value will be used. Check the registry accessibility.
[2018-09-12 09:33:22,545] [-1234] [] [SynapseWorker-11]  INFO {org.apache.axis2.transport.http.HTTPSender} -  Unable to sendViaPost to url[http://...address ommited...]
java.net.SocketException: Connection reset

在我看来，它没有捕获注册表或缓存的端点。

PS：在我的注册表中，地址端点使用dns名称，当发生此错误时，地址端点显示为IP地址。

该如何解决？

在序列和端点下面：

端点ERPEndpoint.xml的内容，顺序如下：

<endpoint name="BennerERPEndpoint" xmlns="http://ws.apache.org/ns/synapse">
    <address uri="http://host/App_Services/PESSOAS/Service.svc/ws">
        <enableAddressing/>

            <duration>30000</duration>
            <responseAction>fault</responseAction>
        </timeout>
    </address>
</endpoint>
