Reload task fails

Hi guys

Our customer is using "Performance Monitor" application. A task created to refresh the app 4 times a day. But we have experienced that this task in some cases fails. The following can be seen in the document and task logfiles:

From document log:
0794 FROM C:\ProgramData\QlikTech\DistributionService\TaskResults\TaskResult_*.xml (XmlSimple, Table is [Root])
Error: XML document must have a top level element.

Do you know why this error occurs and what is it related to (due to)?

Appriciate your reply

can you please share the actual log file? can find this in the document folder with the extension .log

Their we cannot predict the exact reason for the failure.

1.Check the connection once, username and passwords are active.

2.Check whether the Qlikview service account has full access for the document

3.Check for the script errors

Is the XML file updated during the day as well? Perhaps the reload is happening while another process is copying or creating the XML file so it is attempting to open a partially complete file.

Hi Avinash

Thank you for your reply. The Logfiles are enclosed here. The same Logfiles are created every time the task failed.

Regarding your comments:

- Connection is ok. It’s the only task that fails when at the same time other tasks are running (with the same user ID and password).

- The same answer regardin “Qlikview service account” as I mentioned above. It’s ok.

- Regarding the script error I’m not sure whether there is a script error in the application, but if there is an error, so should it not fail every time?

Best regards

Ali

Hi Jonathan

No, it’s not. E.g. the last time the XML file was updated was on Sep. 11th at 06:36. Afterwards all reload tasks failed until today, where I deleted the concerned XML file.

Best regards

There was a bugfix released in QV11.20 SR11 that fixes a problem with empty TaskResult files.(#65972 see release notes here: QlikView 11.20 Service Release 11 now available

Hi Magnus

As I can see in the release note it is about the disabled tasks with an active trigger:

".xml of 0kb gets created in the taskresult folder when task is disabled but has an active

trigger"

but in my case the task is not disabled, but is running 4 times a day. I don't know, maybe the new QlikView version can also resolve my problem.

Thank you for your reply
