Why does this error occur?

Let me know if you need confirmation or if you can tell me the cause.

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.

Stop the QlikView Distribution Service service using Windows Services manager
Browse to C:\Program Files\QlikView\Distribution Service
Locate the file QVDistributionService.exe.config

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 ************ -->

Start the Distribution Service.

Can I set the value to 120?

How much can I increase it?

Is there anything wrong with increasing it a lot?

@qwebnm

You can change the timeout to whatever you want. The problem would be that if there is a "real" reason that the server is not responding, it will take longer for the tasks to timeout and fail.

You need to investigate what the actual issue is. Why are the publisher not able to reach the server?

Is the server stable, is it restarting, network issues?

Below is a troubleshooting guide.

If the value is 120, you mean 120 seconds?
