DSC and QWS Disconnected

[rtamagnini]

I have one Windows server 2019 with QlikViewServer 64-bit Edition (x64) version 12.10.20800.0.

since yesterday, DSC and QWS services go down.
On reboot it's ok for about +/-10 minutes and then it goes down again (DSC and QWS).
when I restart the services it doesn't solve.

I don't have any error messages (I can't find them).
only in QMConsole i got : 3 services down, and DSC@... and QWS... are disconnected.

what can i do ? or where i can see the error ? 

from another post :

1) Is service account belongs to administrator Group.

yes and it's a local user

2) Do you have a valid license

Yes

3) What os you use?

Windows Server 2019 

4) What is the build of QlikView you use.

12.10.20800.0

Hi @rtamagnini,

I would start by reviewing the QMS logs with debug level enabled.  You may be running into a services timeout and if so, there will likely be errors/warnings in the QMS log.

Please note that support for QV v12.10 reached end of life in November 2019, so if you need to reach out to Qlik Support for direct assistance, you'll need to be running a supported version - 12.50 or 12.60.

Best Regards

Hi Chip, Problem solved (apparently).


the server has 2 NICs and was answering for the alternative.

Awesome! Glad you were able to resolve your issue!

That the services after a reboot are shortly running is a good sign that probably nothing essentially is broken. Personally I would watch the task-manager and the service-manager to see if anything noticeable is happing, like a high consumption of CPU + RAM anywhere or if it breaks does the services are further running or are the processes terminated. Usually helpful is also to look for the event-logs from Qlik and the OS.

If this doesn't help you need to look what happens within the n minutes until it breaks. Disabling everything what is not mandatory needed will help to reduce floor-noise on events and maybe also exclude the cause (if all services run on a single machine you may disable the outside network connection and all security tools). Also not setting the service on an automatic start else starting them manually step by step waiting between them - because it's rather unlikely that all 3 services have a direct issue else it's probably one which pulls the other down, too.  Just excluding one possible cause after another ...

Hi Chip, unfortunately what seemed to have resolved, in the end not yet. 
I still have the same problem.

I was thinking about upgrading at the end of this month , but now I wanted to get QkiKServer up and running

i've turn on debug logging on DSC and on QMS.
I have some errors in QMS but not in DSC. Although the 2 are unavailable.
when I restart the server, it usually works fine, but after a few minutes (sometimes 5 minutes, sometimes 1 hour or more) it goes down.

in QMS log i got this error :
