This problem is due to the presence of Cisco bug ID CSCsc48463.
If the Cisco Adaptive Security Appliance (ASA) 5510 is a part of a failover set and the active ASA terminates VPN connections, the standby ASA 5510 can crash when VPN sessions are replicated to the standby ASA.
Note: This problem does not affect the ASA 5520, ASA 5540, or any PIX Firewall platform.
As a workaround, perform one of these steps:
- Remove the standby ASA 5510 from the failover set.
- Download and upgrade the ASA software to version 7.1.1.
