QVDistributionService stops

[#1]

Hi All,

Platform: Windows Server 2012 R2 Enterprise

QV Version : 11.20

For the last couple of weeks we are facing the issue with QV Distribution service, which is getting stopped automatically and only after manual restart it is getting up and running.

I have tried to find any useful information from the log under C:\ProgramData\QlikTech\DistributionService\1\Log, but didn't get any. There is no scripts running in this environment.

The below error message is available in windows event viewer logs

Faulting application name: QVDistributionService.exe, version: 11.20.12742.0, time stamp: 0x54be6947

Faulting module name: KERNELBASE.dll, version: 6.3.9600.18202, time stamp: 0x569e7eb1

Exception code: 0xe0434352

Fault offset: 0x0000000000008a5c

Faulting process id: 0x1c68

Faulting application start time: 0x01d1ee13e39ba3ea

Faulting application path: F:\Program Files\QlikView\Distribution Service\QVDistributionService.exe

Faulting module path: C:\Windows\system32\KERNELBASE.dll

Report Id: 44fcbeb5-5e9f-11e6-80cc-000d3a213974

Application: QVDistributionService.exe

Framework Version: v4.0.30319

Description: The process was terminated due to an unhandled exception.

Exception Info: System.Net.Sockets.SocketException

URL of the QVMC has Localhost instead of server name.

Other services are running fine.

In QVMC under the System > Setup > General> Cluster name and URL contains server name which contains '-'. Is this a problem ?

Checked the below forum

Qlikview server : Services DSC & QVWS down, Reload engine down

Changing of the server name is difficult now.

Any help is much appreciated.

Hi Sudam,

I was experiencing a similar issue.  As a immediate countermeasure, we modified the services recovery tab to trigger a restart of the QDS,

Also, we identified the issue in the event viewer, and created a task to notify support team members...

We have subsequently updated to the latest service release of version 11.2 and no longer experience the issue.

Thanks to community member, who suggested modifying the service recovery tab setting.  Sorry, I wasn't able to find the original link.

Hi Brent,

Thanks for the info. I am bit curious about the change in the QD service properties, whether it will have any negative impact on jobs or other services. Have you encountered any ?

Also as we have found out this as a workaround, is there any probable cause of failure that we can figure out ?

Regards,

Sudam

Sudam,

We haven't experience any negative impact to performance or other services, after making this change.  The service was failing sporadically during non-supported hours, so this just ensured continuous activity until support staff could investigate.

We were able to identify the root cause, but the symptoms haven't reoccurred since we implement the newer SR.

Hi Sudam, what was your approach that  you choose for this issue?  I am having the same issue. Were you able to find out the main cause for this ?

Thanks

Hi Vindhya,

Till now we are unable to find the exact cause of the issue. As per the suggestion from Brent we have automated the QDS restart from service properties, which is actually very helpful. But if any Qlik job is running during the restart of QDS,  the job is getting failed.

We are trying to get more information on this and will post if we find anything positive.

Sudam,

Brent also mentioned that the problem disappeared after upgrading the server to the latest SR. At the moment, you are running SR10. Maybe an in-site upgrade (pretty straightforward) is due?

Best,

Peter

Hi Sudam,

Just an update. The reason behind the QDS stop in my case was because of some scans which were scheduled for windows maintenance. So, whenever this scan is taking place, our QDS is stopping.  Analysis still going on for the correlation between the scan and the QDS stops but as a workaround we have automated the QDS restart from service properties just like what Brent and you have mentioned.

Thanks
