Qlik Analytics: Applications fail to reload with Error: Error: I/O error (filename)

Anonymous — Tue, 16 Dec 2025 12:09:43 GMT

Applications fail to reload with following error:

Error: I/O error (filename)
Execution Failed
Execution finished.

Environments:

- all version
Server - all versions

Resolution:

Antivirus or other process may have a handle on and locking the file and/or causing file corruption. In order to solve this either disable the antivirus completely or ensure that Qlik related files are excluded from the Antivirus scanning.

Hi,
We have crowdstrike Antivirus and as verified it runs on kernel and does'nt need separate exclusion to be set. We are on Qliksense Enterprise version and we have I/O error only for 3 to 5 applications and apart from them there are thousands of Applications running fine. Could you please suggest any other possible reason why we have I/O error for particular qvds and that too very random. I checked for parallel access of file already and it is not the case.

Thanks,

Hello @sks12

I would recommend posting this to our forums to make use of our active community and our support agents.

This would be the right forum: Qlik Sense Deployment and Data Management.

All the best,
Sonja
