    Random Comexceptions (0x80004005) after upgrade to QVS 11

    Tom Tom



      We've just upgraded our Qlikview server from a customer patch 9.00.7652 to 11.0.11154.0.


      We have a quite large installation with around 1.000 reload tasks per day.

      Version 9 worked stable with this amount of reloads, but the console acted damn slow thats why we upgraded to version 11.


      Now we face the problem that the QVS throws randomly Comexceptions:

      Error The sourcedocument failed to open..Exception=System.Runtime.InteropServices.COMException (0x80004005): ErrorHRESULT E_FAIL has been returned from a call to a COM component. atQlikView.Global.SetUserPreferences(IUserPreferences _Preferences) atQVBWrapper.Document.Load(ILogBucket i_LogBucket, Boolean withData)


      Our setup is a dual Xeon (8 cores) with 16GB on W2k3 R2.


      In version 9 we've used 7 simultaneous engines. It seems if I drop the engines the Comexceptions are getting less, but there still there even with only 2 engines running.


      Qliktech support tries currently to figure out why this happens.

      They mentioned that its possible that queued reloads could also occupy a handle to a com object and raise the values above Windows limits of handling com objects.


      We use alot of TaskFinished triggers and so there are quite alot of queued tasks.

      Right now I cannot see how to break this chains without loosing the administrative overview.


      Has anyone else problems with Comexceptions in Version 11 and maybe even better a solution for the problem?


      Best regards,
