Truncated Document Logs generated even for successful Qlikview tasks in QMC

****URGENT HELP REQUIRED****

Hi,

We are using Qlikview 11.20.12904.0 version. We are using it from very long time, but from past few days we are facing the issue below.

Truncated Document Logs are getting generated in Log Location(i.e. in 'QDS Application Data Folder') by tasks in Qlikview QMC, irrespective of whether the task completes successfully or fails. Seeing this issue with almost all tasks.

Could somebody please help ??

Thanks,

Kunika

Are you able to provide an example of these truncated logs? How long are the logs writing before being stopped? Have there been any recent changes in your Qlikview environment?

The correct process for the document logs is they are written locally to your AppData folder while the QVW is being reloaded and then transferred to the root folder once the reload is complete.

Do your document logs look anything like this?

Information   The Source Document was reloaded successfully.
Information   QlikView->Settings->Document Peferences->Generate Logfile in document is set. Enabling Log Copier.
Information   Looking for the document log "\\...\test.qvw" to become available.
Information   Found a document log. FileName=\\....\test.qvw.log
Information   Writing documentLog to \\...\QDS\QlikTech\DistributionService\1\Log\20190330\test\DocumentLog.txt
Information   Slow down logging. Log every <600> seconds.
Information   Reloading
Information    Read Document Log was aborted
Information   Reload finished successfully

Thanks,

Josh

Sorry for late reply.

Yes, the tasks are getting completed properly, their status also gets showed up as Successful in QMC.

Hi @kunika-arora ,

what happens if you try to reload the document in the Desktop client. Are you also getting truncated logs?
It would be interesting to know if there's any difference between the qv.exe and the qvb.exe.
Can you also attach some logs as reference?

Hi @Josh_Berg_Support ,

Very sorry for late reply.

The logs are getting stopped at random times for random tasks. Plus, there have been no changes in the Qlikview Environment.

Yes, the pattern of content in task logs for truncated document logs looks very similar to the content you have posted - with the statements "Slow down logging. Log every <*> seconds"(where * is diff values at diff times, sometimes 2,10,60 etc.) and "Read Document Log was aborted". Does having these 2 statements in the task log point to any known rootcause ? If so what is it and how can it be resolved ??

Thanks,

Kunika

Hi @Daniele_Purrone ,

We are observing that Full document logs are getting generated in the Application folder while the QVW is being reloaded... but the Document logs written/transferred in the QDS log repository are truncated. Plus, this behavior of truncated Document Logs is being observed for some reloads for tasks at random times.

I have attached one task log and corresponding Truncated Document Log. Please take a look at them and advise.

Thanks,

Kunika

I can see on your document log:

Read Document Log was aborted

Looks like the issue mentioned in - https://support.qlik.com/articles/000070420.

That was identified as a bug and the solution was provided in 12.20 IR.

Hi @Albert_Candelario ,

The article mentions about bug in Qlikview 12.10 so, in any way it doesn't relates to our case (as We are using Qlikview 11.2).

Plus, we are using the same version (i.e Qlikview 11.2) in our other environment also but this issue is not there in it... We have been using this version from very long in our both environments.

Could you please advise on what could be rootcause for this and how to resolve it ?

@kunika-arora

Is this issue random or happening on all document logs?

We also saw one case were was impacting 11.20. As usually, this is kind of random, could it be it was already there till it was detected.

Please, provide those details.

Cheers!

Hi @Albert_Candelario ,

The issue is happening for random tasks for random reload cycles.

We have been using Qlikview 11.2 from much longer time, but started seeing this behavior from last couple of months... there was no change made to the environment also so we are at a loss of clue as to what might be causing this.... Further, Our other environment also uses the same i.e. Qlikview 11.2 but its working perfectly over there.

Any hint/clue as to from where we can troubleshoot it/what might be causing it ? Any resolution to this ? Appreciate your help !

Thanks,

Kunika

The most likely thing is a Windows Update to the .Net Framework about the time the issue started to occur, can you confirm on the machine running the QDS if there were any .Net Updates applied around the time the issue started occurring? If so, the best course of action is most likely going to be updating to the latest SR in the 11.20 track, which I believe is SR19 now, that will provide some updates regarding system requirements etc. that may take care of everything here. R&D will not entertain patching SR12 at this point, so this is really about your only option, if we can still see the issue in SR19, then we may be able to look into things further, but this is my best hunch, and I would not really recommend removing updates as you may leave things with some security holes at that point, so I would venture doing the update to SR19 is likely the best option you have at this point. Sorry I do not have anything better, but this is most likely issue from what I can gather from the conversation.
