I just installed two asa 5505. They are running version 9.1(5). They will work for around a week.Then they will freeze up. After reboot they will come back up. All the config is there except my NAT config. Even my network objects are still there just no NAT.
What do you mean with the device freeze? does the device stop passing traffic or it fails? have you tried to access the device using an SSH telnet or console connection when the problem is happening? Do you have logging enabled on the firewall? Are this devices a failover pair or standalone devices?
