QlikView Issue in Automation Task

[balajibc64]

Hi, We are using Qlik Sense and Qlik View. The tasks are setup in the Qlik View and monitoring by Qlik View QMC. Till Today morning around 6.40am our task getting successful. But from 6.50 am onwards the task getting failed, suddenly all the reloaded the job getting failed. 

How to find the issue, exact root cause and where we need to find the logs. Because this is not related to any particular task. After 6.50 am all the reload task failed.

Hello@balajibc64 

The first step would be to look in the task logs to see what error message is recorded. The below article explains how to get the QDS logs.

What version of QlikView are you using? Does a restart of the QlikView Services solve the issue? Restart of the Windows server?

@Maria_Halley Yes. After restart the server now its better. I can able to see the task logs in Qlik View QMC. But how to find the root cause ?

Because those task ran successfully, till 6.30 am. But after that same job getting failed. More over we have nearly 60 reload task .

Hello  @balajibc64 ,

All the tasks failed? Maybe the file sever or the sever itself was not operational or facing a degradation in performance that lead to the tasks failures?

Cheers,

@Albert_Candelario Yes. After restart its working fine. But I can paste few logs details below. 

6/22/2023 12:33:10 PM Warning            The QlikView Engine is Reloading, it will be killed (Please ignore logged warnings/errors about the kill).

Also already pasted the logs above my first failure.

@Maria_Halley @Albert_Candelario Also Please suggest why this issue comes ?

The sourcedocument failed to save.. Exception=System.IO.FileNotFoundException: Could not find file '\\servername\QLIK\QlikviewPRD\SourceDocs\IOC\5.Apps\850777cc-0a3b-4ea7-ae7b-6bb8e3aed8cf_Commercial.qvw.tmp'.

Hello @balajibc64,

What kind of storage are you using?

Are the antivirus exclusions in place?

6/22/2023 12:33:10 PM Warning            The QlikView Engine is Reloading, it will be killed (Please ignore logged warnings/errors about the kill).

Could  you please add the complete log and mask any sensitive information you might consider.

Cheers,

Albert

[balajibc64]

@Albert_Candelario Sure. I will update the logs. Yes Microsoft Defender Antivirus we installed, and we exclude all the respective exe files related to Qlik. 

Also Didn't understand storage are you using ? I mean you are asking about Cluster Storage. We have around 5 servers for all (including Qlik View, Qlik Sense, Qlik NPrinting)  for those we are using common cluster storage. 

[Albert_Candelario]

About the storage I was referring it it is a NAS or a SAN or what kind of file server.

Microsoft defender exclusions might be a bit tricky sometimes, so please do not hesitate to double check that all their different components are excluding the paths you want to.

You can also  run the ProcessMonitor to ensure that no other undesired software is interacting with such folders.
