Hello,
We have been experiencing problems with NPrinting for a month, the Engine service bugs from time to time and we don't know why.
It indicates that it is running but it does not work, the reports run in the vacuum. A report that should take 1 min is not finished 1 hour later.
To get everything back to normal we have to restart the Engine service and often kill it because we get an error message that says we can't stop it.
And it even happens more and more that we have to restart the server.
These crashes happen regularly at this time at least once a day.
We are in NPrinting May 2021 SR2.
Thank you in advance for your help.
Hi,
When you have similar issues do not wait a month. As a customer you have access to the support so open a support ticket with everything we need to understand and reproduce the issue and we will help you directly.
We have too few information to understand what is happening. For example, we don't have the log files nor the version of Qlik Sense you are connecting with. Be sure you are using a supported configuration. Check also the workload of both Qlik NPrinting and Qlik Sense servers. Do a Run Verification on the connection and be sure all ticks are green. Run a preview on the Designer of the reports generating issues and be sure they are correct.
Best Regards,

Hi @Frank_S ,
Thanks for your answer.
What did you mean by a high number of reports?
We are on Qlikview reports and the reports are separate documents with no users on them and they are on a dedicated server.
In terms of Engine and Central server resources, we are around we are not exceeding 50% of the CPU and we are at the 30% RAM usage level.
At the level of the antivirus, it was not set up we have just set it up.
The error occurs randomly, it is not always on the same report.
The services of Qlikview and NPrinting are restarted every week.
For Qlikview what objects are not supported?
Thanks in advance.
Hi,
For performances refer to https://help.qlik.com/en-US/nprinting/May2022/Content/NPrinting/DeployingQVNprinting/Performance.htm
Unsupported objects are listed in https://help.qlik.com/en-US/nprinting/May2022/Content/NPrinting/ReportsDevelopment/Qlik-objects-supp...
If it happens randomly and not always on the same report I think it is related with something temporary. Maybe the workload ? Check the log files, mainly the Engine logs and see if there are error messages.

Ruggero
Unsupported items is a common root cause for NPrinting performance and consistency.
Here is a video describing how to manage unsupported items.
--Unsupported QlikView Document item... - Qlik Community - 1714896
Typically, if you do have unsupported items mentioned in the article/video and the help page shared by Ruggero, then making a copy of the QVW and using the copy for reporting purposes it the path to normalized NPrinting reporting activity.
Further it might be a good idea to have a professional services review of the affected system if after addressing the previous points made that the issue persists. Qlik's PS team can thoroughly evaluate your environment, if needed, from report development to system resource deployment.
Kind regards...
