Unable to log into ESM

[Chakara]

  Over the years, this has happened to me numerous times.  Unable to log into the console, getting an invalid user/pass error message.  Typically we reboot the controller and all is well again.

  Is happening now on a CX system running 4.2.  I have to assume others are seeing this intermittant issue.  What do you do to resolve or prevent it?

  Thanks!

  On a fluke, I decided to try and log in from another computer.  And it worked!  Is it some kind of security lockout of my IP or MAC address?  I did have an ESM session from the locked out machine a few hours ago - perhaps I didn't log out properly.

  Thoughts?
