Work around for the issue has been highlighted below
Description – QlikView service down QlikView Server could not temporarily access the License Key file, becoming an "unlicensed server" and therefore preventing access to the applications. License key was re-applied and the service restored. This issue has not reoccurred since last week. We have moved the license file from Windows file server to local storage on the cluster node
Usually Qlikview fetches the Licensing details from the Internet, However the license can be enabled by having LEA(License enabled file) to run the licensed version offline. This can be one of the reasons for this issue OR
Qlikview needs the Cluster license to have it installed in the Qlikview Server.
Description –Users Unable to access one of the applications This was a file locking issue. We restored application shared object file in order to bring back the services. We have raised a ticket with QlikTech to understand why QlikView Server would lock the file. This issue was also observed in v9. It should be resolved by checking the permission issues from Qlikview Application in the Server. We need to check the permission issue for a particular application in the server. Or It may happen when two Qlikview Application try to read data from the same QVD (Qlikview Data file, which is a native data file exported from Qlikview . The speed on accessing data from QVD is 10-100 times faster than any other Data Source) file.
Description -Users getting random ‘Pure virtual function call error’ when launching Access Point. This issue is with Qliktech as a product issue. Couple of suggestions have been provided by Qliktech but these have not worked e.g. Window patch and upgrade IE Plugin from v11.0 to v11.2.
it’s a browser settings / version related issue , we need to enable/check in the IE client.
