The login/logout thing is a failover issue.. when the backend fails it reverts to pulling a copy of the page you were trying to view from the public cache rather than generating a custom one for you.
I'm seeing extraordinarily high db usage.. I'm trying to diagnose what is going on.
And when I tried to post the above reply, the site took minutes to respond, then did not automatically show me the post in the thread. When I opened the site in a second tab, I was able to see the post in the thread (and, simultaneously, on the tab wherein I wrote the post, I still see the post in the Reply box, as though it never went through).
