I have a pretty old Qlikview Server installation and for the last couple of weeks the QMC has been acting very strange.
All my tasks have status = Waiting, Last execution = Never and Started/Scheduled = Blank. It seems like I'm not the only one who has experienced this issue and I've tried the following solutions found on the community:
Restarting services
Restarting server
Changing two things in the QVManagementService.exe.config (and then restarted services):
QMSChunkSize = 20
MaxReceivedMessageSize = 2621440
Removed the DistributionService folder under ProgramData/QlikTech
None of the above has helped. I cant run tasks manually either, but it seems like some scheduled tasks are running on trigger but this is not shown in the QMC (but i can see the qvb task running and reports are updated). This is not the case all the time though.
