    QlikView Distribution Service (12.10. SR3) hangs up while trying to access LoadBalancer.xml

      Hi @ all ...


      2 weeks ago we upgraded our QV-environment to Version 12.10 SR3 and since then the QV Distribution Service hangs up periodically. It's trying to get ReadWrite-Access to the LoadBalancer.xml but somehow it is locked. Except QV there is no other programm installed on the server. The only solution is to restart the Windows Server. A deinstallation of our antivirus had no effect.


      Here are the times when the first Log-Entry tells me when it hangs: (the time is different so there is no Task causing it)

      The error message we've got from the windows log is here:

      LoadMeasurementStorer: An unexpected error occurred while trying to update the load balancer file.. Exception=System.Exception: Failed to open C:\ProgramData\QlikTech\DistributionService\LoadBalancer.xml with ReadWrite access after 1965 retries. Exceptions= ||    Der Prozess kann nicht auf die Datei "C:\ProgramData\QlikTech\DistributionService\LoadBalancer.xml" zugreifen, da sie von einem anderen Prozess verwendet wird. ||    bei QDSMain.Clustering.ClusterFileHandler.OpenFile(FileAccess fileAccess) ||    bei QDSMain.Support.LoadBalancing.LoadStorage.OpenWrite(Func`2 readWriteLoads) ||    bei QDSMain.Support.LoadBalancing.LoadManager.ReadWriteAccess(Func`2 readWriteLoads) ||    bei QDSMain.Support.LoadBalancing.LoadMeasurementStorer.StoreLoadMeasurement(Double load, Boolean isOverloaded, Boolean hasAvailableRegularQvb, Boolean hasAvailableDedicatedQvb, Boolean preventRegularTask, DateTime timeStamp)


      Would be nice if anybody has an idea.
