I have a pair of PAN 5060 (v.7.1.2) firewalls in HA Passive/Active connected with LACP to pair of core Nexus 9000 switches. From time to time (every hour or few) connectivity to active firewall is faling (can't ping firewall LACP L3 interface ip address from core) for a few sec. When it happens I noticed presence of MAC adddress of firewall on the core switch where passive HA cluster member is connected but failover is not a case here (there is neither no reason not trace of failover). When connectivity is restored I can see MAC address of firewall back on core switch where active firewall is connected.
