无法解决WCF超时错误

Question

I am consistently getting the following error from my QA server:

Message: { strMessage = Class: ShopProcessServiceClient Method: Main Error: An error occurred while receiving the HTTP response to http://xxx.xxx.x.xxx/RyderShopProcessService/ShopProcessService.svc . This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details.

While looking up the associated errors in the above text, they all point to either increasing the send/receive timeout and or maxing out the data values being sent (like maxItemsInObjectGraph="2147483647") . I have done both and still cannot get around this error.

The thing is that when I run the same application with the same settings from within Visual Studio, no error occurs . It only occurs when running on our QA server .

It always crashes when processing the same collection around 170,000 records or so. The next biggest one is around 50,000 records. It did make it past it once, but subsequent tries have failed.

The other thing in the error that interests me is the following: System.IO.IOException: Unable to read data from the transport connection

Also worth noting is the fact that I had a command timeout (for the sql to execute, although after debugging, it takes only a couple of seconds) of 5 mins and when the 5 mins were up, the error occurred. When I took the command timeout out and left it at the default, it crashed at the default value time. This possibly tells me it is having trouble reading the data in the database.

If somebody can inform me what else I might be able to change to get around this error, I would greatly appreciate it.

Answer 1

I resolved the error by updating the send/receive/open/close timeouts. See below.

<binding name="WsHttpBinding_IShopProcessService" closeTimeout="00:30:00"
          openTimeout="00:30:00" receiveTimeout="00:30:00" sendTimeout="00:30:00"
          maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647">
          <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647"
            maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
          <security mode="None" />
        </binding>
