QVS Server service connection problem.

qwebnm — Mon, 26 Jan 2026 18:19:17 GMT

On March 30, 2023, there was a problem connecting to the server's QVS Server service.
The service QVS@njvpd160 was showing as disconnected in the QlikView Management Console, but when inspecting the services running on the server it appeared to be running fine.
I was able to fix this only by restarting the server.
The issue occurred on March 30 between 1:30pm and 2:30pm Server Time (EST).

I would like to know why this problem occurred.
Attached is the event log.
Please let me know if there is anything that needs further confirmation.
Please reply if possible.

Thanks & Regards.

<Server information>
QlikView Server: 12.10.20500.0
Windows Server 2019 Standard

If It happens more often you may investigate the matter. By just occasionally occurrences it's not worth. Causes for such issues are usually a too high workload on the server and/or the network and any authentication failed respectively didn't response in a certain time.

That the services.exe is further running within the task-manager is no sign that the service is working properly - only the QMC will show it.

Thank you.

The first think to check would be the various log-files from QlikView and the OS - especially the application/event/performance-logs. It's not easy to detect if there is only a single issue and the exact time is unknown ...

Hi @qwebnm,

Suggest you start by reviewing the QlikView Management Service (QMS) logs and the QlikView Server (QVS) logs for the date/timestamp of the QVS service showing as disconnected. Secondarily, you could also check the Windows Event Viewer System and Application logs for the same timeframe.

Best Regards
