远程主机使用WCF强制关闭现有连接

Question

我们有一个wcf pub/sub设置,通过netTcpBinding使用可靠的会话,在一台机器上,发布服务和订阅服务都托管在控制台应用程序中,我们得到了上述错误.这台机器在工作组中.我们部署机器的其他任何地方都在一个域中,它工作正常.我对wcf的了解有些局限,刚刚交给我,所以请耐心等待.有没有人对如何解决此错误有任何建议？

完整的例外情况如下:

我的绑定配置如下:

<netTcpBinding>
    <binding name="NetTcpBinding_ISubscriptionService"
             closeTimeout="00:01:00"
             openTimeout="00:01:00"
             receiveTimeout="00:10:00"
             sendTimeout="00:01:00"
             transactionFlow="false"
             transferMode="Buffered"
             transactionProtocol="OleTransactions"
             hostNameComparisonMode="StrongWildcard"
             listenBacklog="10"
             maxBufferPoolSize="524288"
             maxBufferSize="65536"
             maxConnections="10"
             maxReceivedMessageSize="65536">
        <readerQuotas maxDepth="32"
                      maxStringContentLength="8192"
                      maxArrayLength="524288"
                      maxBytesPerRead="4096"
                      maxNameTableCharCount="16384" />
        <reliableSession ordered="true"
                         inactivityTimeout="00:10:00"
                         enabled="true"/>
        <security mode="Transport"
                  transport=""
                  clientCredentialType="Windows"
                  protectionLevel="EncryptAndSign"
                  message=""/>
    </binding>
</netTcpBinding>

端点是:

<endpoint address="net.tcp://localhost:8000/SubscriptionService"
          binding="netTcpBinding" 
          bindingConfiguration="NetTcpBinding_ISubscriptionService" 
          contract="SubscriptionService.ISubscriptionService" 
          name="NetTcpBinding_ISubscriptionService" />

好吧，我知道我的问题是什么了。

客户端应用程序连接到的服务的 mxConnection 为 10。我们还使用 SecureMessaging，listBacklog 为 1。将 maxConnections 修改为 100，将 listBacklog 修改为 200，一切正常。
