Hi

What are you distributing to? QlikView Server, Email or Folder?

[#3]

Distributing to QV Server .

Task Trigger reload is not working , If working the reload fails and the error i see is above. If the reload was successful , I am not seeing anything change on the access Point.

Upgrade to QV was done in new Box running windows 2012.

Thanks

Hi, Are you distributing to a Qlikview Server ? If so, check the permissions of the document folder you are distributing to possibly.

[#5]

Have you checked the Distribution Services logs for errors or warnings?

Located at \QlikTech\DistributionService\[NodeId]\Log.

The Root_[date].txt is generally the one check but please look at all of them in this folder.

In the task on the Distribution pane, re-select and re-apply the Qlikvew Server target setting. That will sometimes fix the error.

Rob - Wow .. Apparently it worked . I have another 15 Tasks to run , I will see if that is the case with others . I will update the thread in a few hours

It would be great if I could get a copy of your QVPR. If it's been failing for a few days, the copy in the backup folder should be fine. I publish a tool

QVPR Analysis http://qlikviewcookbook.com/recipes/download-info/qvpr-analysis/

that I would like to update to automatically diagnose this problem, but I need a corrupted (yours) QVPR directory to test. If you're willing to provide me the QVPR, contact me via the contact form on my website Contact - Rob Wunderlich Qlikview Consulting. If not, I understand.

I looked into spurious failure of a distribution task, and realised from the log that distribute-to-qv-server uses QVP protocol, which relies on the QVS process being alive and well to receive and close the file. If the QVS process is 'in trouble', the file-write fails.

By distributing-to-folder, the problem went away, and also the file transfer is sigificantly faster (ca 1.6 GB file).
