Therefore, I receive a email when it start run, and then after 20 minutes, I receive the email show that the service stop.</p> <p><strong>I really cannot figure out why this happen, why the service stop work every 20 minutes.</strong></p> <p><strong>Does the wcf services stop every 20 minutes, or the Task thread stop every 20 minutes?</strong></p> <p><strong>Will any configuration of IIS7 impact wcf running time?</strong></p> <p>I try to set the receiveTimeout to a every large time amount, and I use asych call to invoke wcf in client side, but this does not make help.</p> <p>Guys, I really need help, many thanks.</p> <p>Following code belongs to a website which calls this wcf service</p> <pre><code>&lt;system.serviceModel&gt; &lt;bindings&gt; &lt;basicHttpBinding&gt; &lt;binding name="BasicHttpBinding_IMailingService" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="24.20:31:23.6470000" sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true"&gt; &lt;readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /&gt; &lt;security mode="None"&gt; &lt;transport clientCredentialType="None" proxyCredentialType="None" realm="" /&gt; &lt;message clientCredentialType="UserName" algorithmSuite="Default" /&gt; &lt;/security&gt; &lt;/binding&gt; &lt;/basicHttpBinding&gt; &lt;/bindings&gt; &lt;client&gt; &lt;endpoint address="http://localhost:92/MailingService.svc" binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IMailingService" contract="MalingService.IMailingService" name="BasicHttpBinding_IMailingService" /&gt; &lt;/client&gt; &lt;/system.serviceModel&gt; </code></pre>
