Qlikview Task failed due to timeout - No Document Log created

No document log seems to be created when a task fails due to a task timeout like:
 

Error: The task "test.qvw" failed. Exception: || QDSMain.Exceptions.TaskFailedException: Task execution failed with errors to follow. ---> QDSMain.Exceptions.ReloadFailedException: Reload failed ---> QDSMain.Exceptions.ThreadPoolJobStillRunningException: Aborting reload. Error: QDSMain.TaskResult ---> QDSMain.Exceptions.TaskTimeOutException: Task <test.qvw> has timed out ||    --- End of inner exception stack trace --- ||    at QDSMain.AbstractReloadTask.Reload(String fileName, IExecutingTaskResult executingTaskResult, String sectionAccessUserName, String sectionAccessPassword, eReloadOptions reloadOption, String variableName, String variableValue, Boolean moniterCpuUsage) ||    --- End of inner exception stack trace --- ||    at QDSMain.AbstractReloadTask.Reload(String fileName, IExecutingTaskResult executingTaskResult, String sectionAccessUserName, String sectionAccessPassword, eReloadOptions reloadOption, String variableName, String variableValue, Boolean moniterCpuUsage) ||    at QDSMain.DistributeTask.PerformExecute(IExecutingTaskResult executingTaskResult) ||    --- End of inner exception stack trace --- ||    at QDSMain.DistributeTask.PerformExecute(IExecutingTaskResult executingTaskResult) ||    at QDSMain.Task.AbstractTask.TaskExecution(CurrentExecutionArgs args)

Environments:

• QlikView 12.10, 12.20 and 12.30

The document logs is not moved in the Distribution folder and in this scenario the the document log stays in:

C:\ProgramData\QlikTech\QlikViewBatch\Script or C:\ProgramData\QlikTech\QlikViewBatch depending on the QlikView version as described in this article:
QlikView 12: Distribution Service is not generating document log until reload completion


Timeouts of tasks can occur due to a too long load statement, a stalling data source, or network issues.
