The earliest recollection of this bug is traced back to PAN-OS 8.1.15 - January 09, 2024. This bug is fixed in PAN-OS versions 9.1.3, 8.1.15. Fixed an issue where a configuration audit created a large number of opresult.out files, which filled up the session/pan/user_tmp directory in opt/pancfg. This caused a slow Panorama response until a device restart was performed or the files were manually deleted from the root of the device.
