WCF timedout waiting for System.Diagnostics.Process to finish
- by Bartek
Dear All,
We have a WCF Service deployed on Windows Server 2003 that handles file transfers. When file is in Unix format, I am converting it to Dos format in the initialization stage using System.Diagnostics.Process (.WaitForExit()). Client calls the service:
obj_DataSenderService = New DataSendClient()
obj_DataSenderService.InnerChannel.OperationTimeout = New TimeSpan(0, System.Configuration.ConfigurationManager.AppSettings("DatasenderServiceOperationTimeout"), 0)
str_DataSenderGUID = obj_DataSenderService.Initialize(xe_InitDetails.GetXMLNode)
This works fine, however for large files the conversion takes more than 10 minutes and I am getting exception:
A first chance exception of type
'System.ServiceModel.CommunicationException'
occurred in mscorlib.dll
Additional information: 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
'00:59:59.8749992'.
I tried configuring both client:
<system.serviceModel>
<bindings>
<netTcpBinding>
<binding name="NetTcpBinding_IDataSend" closeTimeout="01:00:00"
openTimeout="01:00:00" receiveTimeout="01:00:00" sendTimeout="01:00:00"
transactionFlow="false" transferMode="Buffered" transactionProtocol="OleTransactions"
hostNameComparisonMode="StrongWildcard" listenBacklog="10"
maxBufferPoolSize="524288" maxBufferSize="65536" maxConnections="10"
maxReceivedMessageSize="65536">
<readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
maxBytesPerRead="4096" maxNameTableCharCount="16384" />
<reliableSession ordered="true" inactivityTimeout="00:10:00"
enabled="false" />
<security mode="None">
<transport clientCredentialType="Windows" protectionLevel="EncryptAndSign" />
<message clientCredentialType="Windows" />
</security>
</binding>
</netTcpBinding>
</bindings>
<client>
<endpoint address="net.tcp://localhost:4000/DataSenderEndPoint"
binding="netTcpBinding" bindingConfiguration="NetTcpBinding_IDataSend"
contract="IDataSend" name="NetTcpBinding_IDataSend">
<identity>
<servicePrincipalName value="host/localhost" />
<!--<servicePrincipalName value="host/axopwrapp01.Corp.Acxiom.net" />-->
</identity>
</endpoint>
</client>
</system.serviceModel>
And service:
<system.serviceModel>
<bindings>
<netTcpBinding>
<binding name="NetTcpBinding_IDataSend" closeTimeout="01:00:00"
openTimeout="01:00:00" receiveTimeout="01:00:00" sendTimeout="01:00:00"
transactionFlow="false" transferMode="Buffered" transactionProtocol="OleTransactions"
hostNameComparisonMode="StrongWildcard" listenBacklog="10"
maxBufferPoolSize="524288" maxBufferSize="65536" maxConnections="10"
maxReceivedMessageSize="65536">
</binding>
</netTcpBinding>
</bindings>
</system.serviceModel>
but without luck. In the Service trace viewer I can see:

with stack trace:
