A Qlik Compose task may fail during a full load but will run OK after a retry or when started at a different time.
The task error log shows:
main 2023-10-30 08:39:51.396 [engine ] [ERROR ]  Failed to create temporary file for /com/sun/jna/win32-x86-64/jnidispatch.dll library: C:\Windows\TEMP\jna--187113817\jna4331371764969383844.dll (The process cannot access the file because it is being used by another process)
The error indicates that a virus scan or malware scan was active while the Qlik Compose task was run. This locked the files needed.
Option One: Exclude Qlik Compose from virus scans
Exclude the Qlik Compose installation folder from the virus scan. The default path is: C:\Program Files\Qlik\Compose
Option Two: Schedule scans while no tasks run
Do not run any Qlik Compose task to run during scheduled virus scans.
