Top Palo Alto Networks Defects

6.3Defect ID: PAN-311285
( Firewalls in HA conditions only ) Fixed an issue where a memory leak occurred related to the ospfd process, which caused RAM usage to continuously increase on active devices in an HA cluster until the device stopped responding, even after an HA failover.
6.3Defect ID: PAN-302790
Fixed an issue where, with Sender Side Loop Detection enabled, BGP WITHDRAWAL updates were not sent to peers after a route was removed, which caused stale routes to persist in the BGP table of neighboring firewalls.
6.3Defect ID: PAN-302654
( Firewalls in active/passive HA configurations only ) Fixed an issue where, when the HA configuration had multiple logical routers, static or connected routes redistributed into OSPF aged out in the LSDB, which caused the routes to be removed on peer OSPF neighbors.
6.3Defect ID: PAN-301731
Fixed an issue where, when the firewall was unable to establish an SCM connection due to the discovery service returning a 404 error when the device was not yet known to the service, the firewall did not retry the attempt as expected.
