QlikView task fails due to communication with QlikView Server failed (Timedout)!

[Andre_Sostizzo]

A QlikView task fails to reload or finish with the following error:

The communication with QlikView Server failed (TimedOut)!

Example of error from the Task log of the failed task: 
Error    QVClient.Execute failed: System.Exception: The communication with QlikView Server failed (TimedOut)! ||    at QlikTech.NetClient.QvClient.GetMessageDataFromSocket(Byte[] buffer) ||    at QlikTech.NetClient.QvClient.GetMessageSizeFromSocket() ||    at QlikTech.NetClient.QvClient.SendAndReceive(Byte[] request) ||    at QlikTech.NetClient.QvClient.Execute(Byte[] request) ||    at QlikTech.NetClient.QvClient.Execute(String request) ||    at QVSWrapper.QlikViewServer.ExecuteXml(Action`2 i_Logger, String i_Command)

Environment:

QlikView 

Resolution

The timeout can be increased. Note that increasing the timeout may only address a symptom of a different issue, such as network latency, a slow harddrive, or an application that needs to be reviewed and streamlined.

This setting is only available in QlikView 12.10 and later. 

1. Stop the QlikView Distribution Service service using Windows Services manager
2. Browse to C:\Program Files\QlikView\Distribution Service
3. Locate the file QVDistributionService.exe.config
4. Open the file in a text editor and locate the following section: 
   

   <!-- Adjust the time the reload engine waits for the QVS to finish writing to disc during distribution -->
       <add key="SocketTimeOutInSeconds" value="120" />​

   Note: If the section does not exist, add it under:

   <!-- ************ QlikView Engine and Distribution Settings ************ -->

5.  Start the Distribution Service.
