We have the strangest thing on our QlikView server. After a certain timeframe (mostly days) all of our reload and distribute tasks fail with the following message (generated by QlikView Distribution Service v10.0.9061):
10-10-2011 15:05:07 Error The sourcedocument failed to open.. Exception=System.Runtime.InteropServices.COMException (0x80004005): Error HRESULT E_FAIL has been returned from a call to a COM component. at QlikView.ApplicationClass.SetUserPreferences(IUserPreferences _Preferences) at QVBWrapper.Document.Load(ILogBucket i_LogBucket) 10-10-2011 15:05:07 Error The document failed to open. 10-10-2011 15:05:07 Error Document could not be opened 10-10-2011 15:05:07 Error Reload failed because the document could not be opened successfully. DocumentState=CouldNotOpenDocument 10-10-2011 15:05:07 Error Reload failed. Distribution skipped. 10-10-2011 15:05:07 Error The task "Reload & Distribute My app" failed. ErrorCount=5 |
It seems to start without any clear reason. To solve it we tried to restart each individual QlikView service, but this had no success. We have tried to stop all the QlikView services and then restart them one by one, but this also did not solve the issue. The tasks keep on failing in their reload. The only thing that resolves the issue is rebooting the server completely.
After the reboot everything works like normal and the tasks work again. But after some time, the error occurs again.
I have looked into the Event Viewer and the only thing that I can find is the following error message:
Request failed (Alternate get): System.Net.HttpListenerException: An operation was attempted on a nonexistent network connection
at System.Net.HttpResponseStream.Dispose(Boolean disposing)

This seems to occur right before all the reload error messages. The message is generated by the QlikView Management Service.
The files that are reloaded are stored on a local disk of the server. When trying to do the reload on the server itself, it works like a charm. But letting when the tasks execute, they fail.
Because the restarting of the QlikView services do not seem to have any effect it seems like there is a dependency to something else, but I can't figure out what that could be.
Does anybody have a clue?
