套接字异常 - WCF [英] Socket Exception - WCF

问题描述

我在我的WCF服务中遇到异常后得到了。



套接字连接已中止。这可能是由于处理消息的错误或远程主机超出接收超时或基础网络资源问题引起的。本地套接字超时为'00：00：59.9355444'。



服务器应用程序配置

Hi ,
I am gettgin following exception in my WCF service.

The socket connection was aborted. This could be caused by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying network resource issue. Local socket timeout was '00:00:59.9355444'.

推荐答案

通常我会说这个错误你是通用的，通常会隐藏另一个错误，错误没有显示。



但在你的情况下，你的超时是如此接近一分钟，我认为你达到了这个限制：



sendTimeout =00:01:00



尝试延长这段时间，看看是否需要更长的时间。



It很简单，可能需要花费更长的时间来生成服务器响应。



如果不是，则下一步是跟踪实际呼叫。您需要配置跟踪，然后查看跟踪输出以找到真正的异常。

Normally I would say this that error you have is generic and generally hides another fault, not shown by the error.

But in your case, your timeout is so close to a minute, I think you're hitting this limit:

sendTimeout="00:01:00"

Try extending this time and see if it takes longer.

It could, quite simply, be taking longer the 1 minute to generate the server the response.

If not the next step is to trace the actual call. You need to configure a trace and then look into the trace output to find the real exception.

嗨Stephen，



最后我今天早上得到了突破。

这是最终的伎俩。



1.在服务和客户端配置中添加了这些行为。

Hi Stephen,

Finally I got the break through, today morning.
This was the eventual trick.

1. Added these behaviors at both service and client config.

<behaviors>
<endpointBehaviors>
  <behavior name="endpointBehavior">
    <dataContractSerializer maxItemsInObjectGraph="2147483647"/>
  </behavior>
</endpointBehaviors>
</behaviors>

2.在客户端和服务器配置中将这些值更新为最大大小。

2. Update these values to maximum size in both Client and Server config.

<binding name="tcpBinding" receiveTimeout="00:15:00" sendTimeout="00:15:00"  maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647" maxBufferSize="2147483647">
          <security mode="None">
            <transport clientCredentialType="None" protectionLevel="None" />
            <message clientCredentialType="None" />
          </security>
        </binding>

a。 maxReceivedMessageSize

b。 maxBufferSize

c。 maxBufferPoolSize



再次感谢您的帮助。

a. maxReceivedMessageSize
b. maxBufferSize
c. maxBufferPoolSize

Thanks once again for the help.
