That's SR5 and the latest one is SR12. There has been a fair bit a code changes in this area so I would recommend you to upgrade.

If this is not possible my suggestion is to check the task definition. Is it using anything special like repeat variables/reductions etc? Try removing piece by piece to identify what issue.

The error is a general Windows error, making it hard to easily see whats wrong.

Hope this helps.

HI,

I would have to agree with Magnus on this. Once you upgrade and the problem still exists, I would contact support for help

Thanks Magnus for reply

it is not possible for me to upgrade it, the load is simple and there is no any repeat variables/reductions in it.

Whenever i restart the services it work fine for that day and on the next day it fails again.

Like Bill states, you will need to upgrade to be able to get support on this one.

There is always the possibility to have Distribution Service (QDS) on Debug logging and trying to figure it out by looking at the log rows preceeding the error. Also look at the general log files for QDS to spot other errors or warnings.

The source document the task is associated with is stored in QVS (path starting with "qvp://").

When Distribution Service is running the task it will query the QVS to retrive the physical path to the qvw file. QVS does not seem to find the document.

Please check QVS logs and also verify that the source document is available.

Re: Error. Exception: QDSMain.Exceptions.DistributionFailedException: Distribute failed with errors to follow. ---> System.ArgumentNullException: Value cannot be null.

Yes the source document is present at the root folder.

Can you confirm that the task is pointing at Source Document with a file path starting with "qvp://"? Find the matching Task_[GUID].xml under the application data for Distribution Service.

This tells us that is a task created without Publisher license. Are you currently running without Publisher license?

Maybe you have tasks remaining in your system from before putting on the license.

Hi Magnus,
