Nexus 5672UP Can't Log In

[willinit]

On my Cisco Nexus 5672UP, I'm getting the following steam of messages and can't log in both locally and remotely. Locally I just get "Login timed out". Remotely I get "Connection closed". Looking for any suggestions on how I can actually get logged into this device without (hopefully) having to reboot the switch.

 - It seems like  your authenticating servers are not available (radius?) , do you still have a local account ?

The log messages are clear that there is a problem accessing your authentication server and when it attempts local login there is a problem

 So I think there is a 2 part problem.

1) why is using the authentication server not working?

2) why is the backup method of using local authentication not working?

I believe that @marce1000 has asked a crucial question - is there a valid local user ID and password configured?

I wonder if there is some issue, perhaps a memory leak, that is impacting the ability to login to the switch? Are there any other unexpected messages in the logging output?
