I figured out the problem with the huge number of logged members.
I closed my BW window without logging off and my login remained active for a good amount of time. I think there is a bug where the server does not check by sending ack on a periodic basis or something specially when there is no action from an account. I am guessing that the huge amount of logged usernames has no bearing on the server processes since we are not experiencing slow down.
I was able to log in using a different proxy while my account was still up so this shows that it's not checking based on user name so technically there could be a mutiple session possibility which is not good for securing many aspects of the site. You see what happens when you don't use GM products? I bet ya if we used Onstar for BW it will solve the problems.
