The QlikView Document (.qvw) update date on the AccessPoint is incorrect. The year might display as 2367 or 5824 or 4111
The issue is observed mostly with tasks that are not meant to be run on a schedule but are only triggered on demand.
Resolution:
Delete the .META files found in the QlikView document storage directory and run the task to recreate it.
Please Note: If DMS mode is used, this will also clear out permissions!
