Reference for QlikView coredump dmp ctxf variables ?

fredericvillemi — Mon, 26 Jan 2026 18:19:17 GMT

Hello,

On my QlikView server I have frequent crashes mostly based on bad developement of Apps.

But I would be happy to be able to find some precise root causes based on .ctxf files.

Is there a reference somewhere for the structure of the ctxf files ?

Here is one below, I would be happy to have more details about how i can use it to find which element of the document is bad

Thanks

@fredericvillemi

To analyze the dmp files you need to have access to the QlikView source code. So this is not something we can share.

Hmm I'm not talking about the big dmp files but just about the ctxf file where there are many clearly defined items.

I can see the name of the document and the user but what does "Result too large" means ? is it because of a bad chart ? is there a list of "Errno" ? does the "Method=ListBox::GetLayout" means the problem is a listbox ?

Thanks

@fredericvillemi

if you know that there are specific documents that causes the problem, you can use the document analyzer to do a "health check".

https://community.qlik.com/t5/QlikView-App-Dev/QlikView-Document-Analyzer-update-3-9/td-p/1519546

It is also useful to go through the QlikView Server event log. (check the verbosity you are using)

It looked a bit like an attempt to influence the impact of these badly designed applications instead of fixing the root-cause and optimizing them or to re-design them.

Sorry, I don't understand what you mean.

I have an application which crashes the server and creates a dmp and a ctxf log.

When it crashes, the ctxf log gives information about which user and which document (out of 100s) was the source of the crash. I would like to know more about the other parameters of the log (like errno or Result too large) to be able to find what I need to fix in the document.

I have said that the server crashes because of bad devs. Sometimes it is obvious when i open the .qvw and i don't need to investigate to know what to fix. But sometimes, I can't find what has been done badly and I would be happy to use all existing logs to be able to know why the server is crashing.

I'm admin of the server and i don't develop all the documents. Some tricky bad devs are not always seen in testing and that's why I would be happy to avoid those crashes

And I must say that even if the development is not good on some apps, QlikView server should not crash and it should have some protections to avoid that .. finding how to finetune some apps may give a better image of our tools 🙂

@fredericvillemi what version are you on

Re: Reference for QlikView coredump dmp ctxf variables ?

fredericvillemi — Tue, 05 Dec 2023 13:00:43 GMT

Thanks for those tips Maria,

in the event log i only have :

Notice Engine: Server aborted. Reason for restart: Internal inconsistency, type CPV, detected

What does Type CPV mean ?

Thanks

to do crash analysis we have to engage R&D, and they will not work with an unsupported version, please reference: https://community.qlik.com/t5/Product-Lifecycle/QlikView-Product-Lifecycle/ta-p/1826339

There are various measurements within Qlik to prevent server-crashes but they won't fetch each occurrence. Especially the server-objects and their storage within the shared-files is common cause for issues - which are not obvious by investigating the application with the desktop client.

For testing reasons you may remove the shared-file (after a BACKUP) and/or disabling server-objects and/or trying to repair the file (within the power tools are viewer and a repair-tool available).

Thanks for the link,

Unfortunately we have no immediate plans to migrate to a newer version ..

And I understand no parameters of the .ctxf are documented if only R&D can use them ..

fredericvillemi — Tue, 05 Dec 2023 14:34:57 GMT

Unfortunately, I have checked the settings and there are no server objects as we have denied them on this app. I have already seen that it may be the source of many issues.

I'll keep on testing this app.

I would look into the data-model and making sure that there are no synthetic keys and/or circular references. Further if there are any island-tables that they aren't used in the UI in an association against the normal data-model. Also reviewing all calculated dimensions - especially those with aggr() and the ones which aren't directly applied as object-dimension else anywhere in groups/labels/titles and so on.

Thanks for these tips, I will look at those items in the document, the (quite small) document usually works fine and I haven't seen mistakes for the moment but there is something bad somewhere 🙂
