WCF超时问题？ [英] WCF Timeout issue?

问题描述

我有一个有点长采取基于WCF的过程。 WCF服务，如果有任何帮助它运行在Azure上。我相信这个问题有超时的事：

I have a somewhat long-taking WCF-based process. WCF service runs in Azure if its of any help. The issue I believe has to do with timeouts:

1）的WinForms客户端在绑定节以下的.config设置：

1) Winforms client has the following .config setting in the binding section:

 <wsHttpBinding>
  <binding name="XXX" closeTimeout="00:05:00" openTimeout="00:05:00"
   receiveTimeout="00:10:00" sendTimeout="00:10:00" bypassProxyOnLocal="false"
   transactionFlow="false" hostNameComparisonMode="StrongWildcard"
   maxBufferPoolSize="10000000" maxReceivedMessageSize="10000000"
   messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true"
   allowCookies="false">
   <readerQuotas maxDepth="255" maxStringContentLength="8192" maxArrayLength="16384"
    maxBytesPerRead="4096" maxNameTableCharCount="16384" />
   <reliableSession ordered="true" inactivityTimeout="00:10:00"
    enabled="false" />
   <security mode="TransportWithMessageCredential">
    <transport clientCredentialType="None" proxyCredentialType="None" realm="" />
    <message clientCredentialType="UserName" negotiateServiceCredential="true" algorithmSuite="Default" establishSecurityContext="false"/>
   </security>
  </binding>
 </wsHttpBinding>

2）WCF服务具有以下绑定区段在web.config

2) WCF service has the following binding section in the web.config

   <wsHttpBinding>
    <binding name="XXX" maxReceivedMessageSize="10000000" sendTimeout="00:10:00" receiveTimeout="00:10:00" closeTimeout="00:10:00" openTimeout="00:10:00">
     <security mode="TransportWithMessageCredential">
      <message clientCredentialType="UserName" establishSecurityContext="false" />
     </security>
     <readerQuotas maxArrayLength="2000000" maxBytesPerRead="10000000" maxStringContentLength="10000000" maxDepth="255" />
    </binding>

   </wsHttpBinding>

3）我在WCF（一般为2分钟）一个长运行的方法。客户端调用该方法，和那些执行较长再用1分种越来越抛出带有异常。这是最内部异常：

3) I have one long-running method in WCF (generally 2 minutes). Clients call the method, and those that execute for longer then 1 minute are getting thrown out with an exception. This is the most inner exception:

  <InnerException>
    <Type>System.Net.Sockets.SocketException</Type>
    <Message>An existing connection was forcibly closed by the remote host</Message>
    <StackTrace>
      <Frame>at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size)</Frame>
    </StackTrace>
  </InnerException>
</InnerException>

4）WCF调用自身成功完成，但（我都开始/结束登录服务器端）。如何避免异常？

4) The WCF call itself completed successfully, however (I have both Start/End logged on server side). How do I avoid the exception?

感谢您！

推荐答案

在Windows Azure负载平衡器60秒后终止空闲连接。

The Windows Azure load balancer terminates idle connections after 60 seconds.
