"Insufficient quota to complete the requested service" seen in the logs when something fails

[Yoichi_Hirotake]

Around a failure of some kind (file access, reload, ...) the error message "Insufficient quota to complete the requested service"  is  recorded in a Qlik product's  log file

Environment:

• QlikView Server, any
• Qlik Sense Enterprise on Windows, any
• Qlik NPrinting, any

Cause:

This error is not caused by the Qlik Product, and needs to be investigated on the Operating System level: it is just a generic error pointing out to exhaustion of resources.
This might include:

• CPU
• RAM
• disk I/O queues or space (temp files overloading, etc..)

Resolution:

It will be necessary to monitor each sort of resource usage, both on the QlikView Server and fileserver, to understand what might be causing the issue.

In particular, the fileservers should be therefore investigated by the internal IT around these areas:

• Disk Space
• Quota management software which may be used to restrict access
• File Permissions for the folder/files that are getting accessed in that moment, as specified in the log files
• generic resource usage on the file server
• antivirus (check this article for the required exclusions) or any other  software that might prevent file access
