The earliest recollection of this bug is traced back to PAN-OS 8.1.12 - January 09, 2024.
This bug is fixed in PAN-OS versions 8.1.12.
Fixed an issue where vsysadmins were unable to view the locks on all the virtual systems they were assigned to. To view the locks in CLI run the new show commit-locks vsys and show config-locks vsys CLI commands.
