You need to have at least two different logged in users to reproduce 
this error. Just open some other browser and log in with a different 
username.

The logout is imho related to the authentification chain: You are always 
logged out if you increase ['BE']['lockIP'], but not if you decrease 
this setting. I don't think this is a problem here.

I can not reproduce this after a successful re-login, it shows '-' for 
me with lockIP=0


There is one issue left: If I set ['BE']['lockIP'] = '4' I still get the 
gethostbyaddr() warning.
