I have ASA 5520 with 8.0(2) and using for SSL with 50 user liscence. SSL Clients are using Windows VISTA. Clients can either connect through Tunnel mode and Browser mode.
It works fine but suddenly ASA reject all the SSL sessions and even no new session can be established. For clients it gives "Logon Error".
ASA again start accepting SSL connections only after reload.
I am planning to upgrade it to 8.0(3) but not sure, if it will help to resolve this problem. Please suggest
