i encounter the problem not be able to ssh to my ASA5510 anymore. the log shows a entry with "Resource 'ssh' limit of 5 reached for context 'single_vf'". i found already some posts on the internet stating to regenerate the rsa key. i did it with "crypto key generate rsa modulus 1024", but this didn't helped a bit. i'm still getting the error in the log and not able to ssh to it. i found a post saying to 'zeroize rsa' first, but i have no idea how to do that. any suggestions?
