Task reload failure

[#1]

Hello,

Few of the recurring tasks fail at random in my environment and when checked for the Log folder, i could not find file which captured the failure. What could be the reason for this behaviour?

However i have got the error from the tasks list and it is pasted below.

Message from ReloadProvider: Task failed due to timeout getting engine connection

Which version of Qlik Sense are you on? Regarding your questions:

a) I could not find file which captured the failure. -- The error files you can find on Scheduler node at "E:\Qlik\Sense\Log\Script" or in archived logs (E:\Qlik\Sense\Repository\Archived Logs) at central node.

b) Looking at the content looks like task failed after 30 minutes. You might want to increase this parameter in QMC > Scheduler > Engine Timeout (in mins)

Thanks for your reply Jai.

a)  I can see the log files in the central node, but could not find the one which captures the failed task. Why is it so?

b) Will there be an impact on other related things if i just increase the timeout parameter? What all should be considered before i increase the timeout?

[jaisoni_trp]

a) Did you try searching with app id? also have a look at trace folder of scheduler node.

b) This setting is implemented globally so you will have to consider about total # of tasks, concurrent tasks, # of scheduler etc.

a) Yes i found the log entry but it says that the execution finished. Could not find the one with failed error.

Thanks.

Does this "execution finished" within the timelimit of 30 minutes? I would expect to find the failed log files in the same path.

Hi Ganesh...

Create a task from QMC to the app in question with once only trigger and start the task from the QMC tasks... Once it fails click on the info it will give option to download script log.. save on your desk top and open it .. will open in text file format..

Thanks

Ganesh,

We are experiencing the same situation and message. Reviewing this post, it appears it was never answered .

Was there a resolution?

we are facing the same problem here...

and when we click "start" and re run the task in a different time, it works

does anyone can help?

thanks in advance

igor,

We were able to resolve this problem by staggering the task execution start times. We had numerous tasks that started at similar times, but definitely overlapped. Granted, they should have "queued", but did not because of this failure. We also have the Qlik SAP Connector. Though not verified, we suspect the connector (which does not perform as well as a direct SQL connector) may have had something to do with the issue as well.

Finally, we also cleaned out our Qlik log files which were quite large (we had never cleaned them out).

Hopefully, some of these actions will help resolve your issues as well!
