How to monitor error "Cannot open file" / "Failed to open file in write mode"

[grayfloor]

Hi Community

We regularly have an issue that one file fails to open so the task fails. The error in QMC>Tasks looks like this:

Spoiler

20240117T135530.206+0100 Error: Cannot open file: 'Lib://xxxxx.qvd' (Native Path: xxx.qvd
20240117T135530.206+0100 System error: Failed to open file in write mode for file: xxxx.qvd)
20240117T135530.275+0100 Execution Failed
20240117T135530.281+0100 Execution finished.

 I want my monitoring tool (PRTG) to search log files for this issue so that I can react on the error before the customer finds the problem but cannot find any log file where this error is listed except downloading the file from QMC>Tasks. 

Is there a log file where this error can be found so I can monitor this file?

Thanks

@grayfloor This says QVD not loaded correctly, In the first place If I can see error there is no Connection defined towards your source?  Working with QVD files | Qlik Sense on Windows Help

Hello @grayfloor ,

It seems you are having problems with QVD's being locked, please refer to the following articles:

Concurrent Read and Write from/to a QVD file may result in one of the tasks failing

And, the error you mentioned will appear in Qlik Sense Script logs. For more information, please read How to find the Script (Reload) logs in Qlik Sense Enterprise on Windows
