From you previous logs, the client fails at signing with rsa-sha512. A long shot may be that there is a buffer overflow somewhere due to sha512. Have you tried eliminating this signing algorithm from server (or client)? Unfortunately I don't control the server (or I wouldn't be using AnyConnect :P) but maybe No?l or I can try disabling RSA-SHA512 on the client side and see if that changes anything.
