Addressed PAN-OS 12.1.2

PAN-242777

Fixed an issue where users previously reported limitations due to session count caps when utilizing Web Proxy features on PA-5400 Series Firewalls. To address these performance complaints and support higher traffic volumes, we have increased the maximum session capacity on specific PA-5400F series platforms, leveraging available system memory. This update ensures greater capacity and stability for high-volume environments.

The supported session limits are:

Platform Max Sessions
PA-5410 95K
PA-5420 95K
PA-5430 95K
PA-5440 225K
PA-5445 250K
PA-5450 1.28M

PAN-291499

VM-Series firewalls on Amazon Web Services (AWS) environments only

Fixed an issue where newly deployed firewalls were unable to connect to the Strata Logging Service (SLS) until after a reboot, license fetch, or management server restart.

PAN-288726

Fixed an issue where the useridd process stopped responding due to a Security policy rule ID being set to 0, which caused the last configuration retrieval to fail.

PAN-287133

Fixed an issue on the Panorama web interface where assigning a policy rule to a group at the top or bottom of the list changed the order of other policy rules.
