Cisco ASA Audit Event: 305008

305008: Free unallocated global IP address

Cisco ASA is a security device that provides the combined capabilities of a firewall, an antivirus, and an intrusion prevention system. It also facilitates virtual private network (VPN) connections. It helps to detect threats and stop attacks before they spread through the network.

Message: %ASA-3-305008: Free unallocated global IP address.

Event 305008 is generated when the ASA kernel detects an inconsistent condition while trying to free an unallocated global IP address back to the address pool. This abnormal condition might have occurred if the ASA had been running a Stateful Failover setup and some of the internal states had been momentarily out of sync between the active unit and the standby unit.

How could you resolve this situation?
