Nprinting server: "Allocated memory exceeded"

Matthew von Brockdorff Oct 21, 2015 3:36 AM

Hi,

I am having a strange issue with Nprinting server.

When I run the Nprinting report manually from the client side the pdf report in the output folder is created successfully. However, when I set a schedule for the report to be automatically generated by the Nprinting server, every chart is showing an "allocated memory exceeded" error. It was running successfully a couple of days ago.

Anyone have a clue what might be causing this problem?

Thanks!

Strange!! Did you check whether your NPrinting server is up and running fine.
I would suggest to restart your NPrinting server once and run the task again .

  I've been trying a lot of things but nothing seems to work! The problem is also happening with different NPrintng files although all are connected to the same source (QVW). I also restarted the service but all in vain.

      I think it something from the server side. In fact when I manually run the report from the Nprinting client it works fine. I have connected different .nsq (Nprinting files) with different .qvd sources to troubleshoot but I'm still having the same problem. I re-installed the nprinting service on the Qlikview server but still nothing. I am running out of ideas no .
      
      Anyone have experienced this issue or have an idea what might be causing the problem?

  Hi Sudhakar,
  
  Sorry I forgot to post my solution to this problem. I solved this problem by logging in the Qlikview Server, opening the QVW (the nprinting source) through the server, and reload the document from the server. I thing you can also reload the QVW directly from the QMC.
  
  The problem, in my case, has something to do with licenses.
  
  Regards,
  Matthew

I had a similar issue. A combo chart was working for my colleague but when I opened it, It gave me "Allocated Memory Exceeded" error. I figured the problem was my QV version.

The problem got resolved after upgrading to the Latest Version of QV.

Hi All,

It seems that another root cause could be Proxy related. When the network is slow it fails in displaying images. I have seen the proxy issue in our environment in 3 different scenarios. In my case, after chaning the proxy server address, the problem has vanished !!

Cheers,

Hi All,

Does you application have secction access?
Does it use datareduction based on section access?

As you are running task as a service account i would suggest using the same account when testing or even building QlikView app. That way if there is a field missing (maybe OMIT) i section access, or variable is not calculated which needs to be a part of expression in charts.

I would review expressions and look for a gaps which can potentialy cause a chart to fail calculating and rendering.
Consider also reviewing expressions like those for dimension/expression text, background colour or format as well as those for captions!

I came accross this issue couple times where there was wrong text format applied '<B>', without quotes...

regards
Lech

BTW. What version of NPrinting are you running this task in.
are those charts based on "Always one selected value" selection maybe?
Remember that NPrinting 17 removes all selections before task execution so you would need a filter to put that selection back! Also remember that if this is a case then it would put lots of stress on Qlik server as it will try to calculate expression which is designed to be calculated in different way.

cheers
