Distribution Service Stopping without Reason

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

Recently we upgraded to QV 11.2 SR12.

Every Sunday since upgrading to this version (4 weeks) the Server stops processing between 3:30am and 5:00am. Upon investigation, the server displays as active, but the only option in the service screen is the 'Start' service button. In the QMC, the message 'Publisher is down' is displayed.

After starting the service, everything is fine until the next week.

I've reviewed all the logs and nothing indicates why or when the service stopped. The next entry is the 'Initializing QlikView Distribution Service... Please wait..', after the service is started.

Is this a known issue in SR12? Has anyone else experienced similar symptoms?

I'm upgrading to SR13 at the earliest availability, but am curious if this will address the issue. Is anyone seeing this issue in SR13?

Thanks for your support,

Have you looked into the windows event-logs? Quite often you will find there the reason or at least hints to what is happens.

There was an event from the Service Control Manager source with the following description 'The QlikView Distribution Service service terminated unexpectedly. It has done this 3 time(s).'

These 2 TermDD source events were recorded a minute apart, prior to the Distribution Service failing...

'The Terminal Server security layer detected an error in the protocol stream and has disconnected the client.'

'The RDP protocol component "DATA ENCRYPTION" detected an error in the protocol stream and has disconnected the client.'

Doesn't really hint at a cause though.

Thanks for the suggestion,

Probably one for Qlik Support.

I agree, but they haven't offered any suggestions yet.

Set your service recovery settings to restart on all failures As a workaround.

Maybe contact your Account Manager to see if he can up the priority. You are effectively System Dead every week.

Rob's suggestion of the auto restart also does sound like a good workaround.

The consistent failure at the same time on the same day every week may be an indicator for the reason. Is a reload task running at that time? Is something else grabbing excessive amounts of memory? Is there enough memory available for the QDS to operate?

Can you switch the QDS Log to debug logging and post the Root_YYYYMMDD.txt.file of the next failure?

Best,

Peter

Considering the consistency of the issue and the time it occurs, it might be worth checking if there are any other maybe non-QlikView activities happening at the time. Server maintenance, backup, windows update or some other routine out of hours task.

Peter,

The server does not use significant amounts of memory during these issues, and the QDS has plenty of additional memory it can consume if necessary.

The QDS log is set to debug, but there wasn't any error or shutting down messages. Presumably, since the service failed unexpectedly, a log entry wasn't generated.

Another symptom I just identified, is a reload task was aborting for several hours prior to each failure. The task is different each time. I've identified an instance that occurred during a different day and time, so I don't think this is a specific task related error.

Thanks for your response,

Always worthwhile making sure you have the latest recommended Windows patches applied.

I had a problem with an earlier QV12 SR with the Distribution Service becoming unstable. This was caused by a .net bug that was fixed in the recommended Windows Service Pack.

Nice one, Bill!

We did indeed install all the latest Windows updates on the largest QlikView customer platform before upgrading to SR12. Warned by another post somewhere in the community..

I agree with Bill. The messages in the event log point to problems in your Windows environment rather than the Distribution Service itself.

Hi Bill Bill Markham

Do you remember which service pack you had to install?

Jerry

It was back in Oct 2014, see this thread Publisher tasks steadily get slower until Windows Services restarted

Also refer to this document by Qlik, https://qliksupport.force.com/QS_CaseWizardKnowledgeArticle?Id=ka6D000000001HhIAI

It was on Windows Server 2003 Enterprise, and was sorted by Windows update 2600217, https://support.microsoft.com/en-us/kb/2600217

Your symptoms do not match that ones I had. But I thought it worthwhile mentioning.

Thanks.

We are just about to start testing and rolling out SR9 to SR13 patch at my customer. Large environment, so I like to find possible problems before instead of after. 🙂

Bizarrely we have just upgraded to QV11.2 SR12 too and our distribution service has also crashed 3 times in two weeks. Always overnight but other than that no pattern. Makes me wonder if we have the same problem?

Bill,

Our windows environment is regularly being updated with the recommended patches by Microsoft, but they appear mostly security based.

Is there a list of patches that Qlik recommends for their ? I've searched the community, Qlik System requirements, release notes and reference manual, but I wasn't able to find a list.

Thanks,

Hi Andrew,

Do a netstat -an | find "666" and if you see the below contact support for a patch. The issue is if a port scan is done and it hits port 666 it will cause QDS to Crash.

c:\>netstat -an | find "666"

TCP 127.0.0.1:666 0.0.0.0:0 LISTENING

TCP [fe80::317d:51ac:7475:c545%10]:666 [::]:0 LISTENING
