WCF Timeout Exception on IIS hosting

Question

Thanks in Adavance. I am getting timeout exception after 5 minutes eventhough all timeouts are set to 10 minutes. Wcf is hosted in IIS. Client config is as below '

<netTcpBinding>
<binding name="TcpAuthBinding" closeTimeout="00:00:05" openTimeout="00:03:00" receiveTimeout="00:10:00" sendTimeout="00:10:00" transactionFlow="false" hostNameComparisonMode="StrongWildcard" maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">
<readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
<reliableSession ordered="true" inactivityTimeout="00:10:00" enabled="false" />
<security mode="Message">
<transport clientCredentialType="Windows" protectionLevel="EncryptAndSign" />

This is intermittent issue. In service I am fetching data from database server. Exception is as below
