我在
Windows Server 2003机器上的单个Windows服务中托管了两个WCF服务.如果Windows服务需要访问任何WCF服务(例如发生定时事件),则它将使用暴露的五个命名管道端点之一(不同的服务合同).该服务还会为两个服务中的每一个公开HTTP MetadataExchange端点,并为服务器外部的用户提供net.tcp端点.
通常情况下,事情会很好,但是每隔一段时间,我会收到一条像这样的错误消息：
System.ServiceModel.EndpointNotFoundException: There was no endpoint listening at net.pipe://localhost/IPDailyProcessing that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException,if present,for more details. —> System.IO.PipeException: The pipe endpoint ‘net.pipe://localhost/IPDailyProcessing’ could not be found on your local machine.
— End of inner exception stack trace —

它不会可靠地发生,这是令人生畏的,因为我不能重复,当我想.在我的Windows服务中,我也有一些定时事件和一些文件监听器,但这些事件是非常罕见的事件.有谁有任何想法为什么会遇到一个问题？任何帮助将不胜感激.
