ADSL  RSA host key retrieval failed

Posted on 2009-02-21

We have a Cisco ADSL and I was wondering why this error is getting logged.
"Fail to establish SSH session because RSA host key retrieval failed."

Our clients are remote VPN clients and they are getting disconnected from the network intermittently.  Should this be a security concern?
Thanks in Advance

    Hello GetRdone,
         Is this a recent issue you encounter? Is this an SSH issue or VPN issue? Please elaborate more

    Deleting existing keys and regenerating may help. Also make sure hostname of router and domain-name is set.
    crypto key zeroize rsa
    crypto key generate rsa general-keys modulus 1024

    It is a recent issue.  The VPN is disconnecting the remote client pc's XPPro.
