Haha...more like we need to buy red bull for our computers No more slowdown issues right? Or maybe it would be too fast then

Well I've been up for days now...I THINK. I am faced with a very strange issue now. I left my computer on since Saturday morning, left for the weekend and came back now (it is now Monday afternoon where I am). Before I left, I had nothing running except for Transmission downloading 4 large torrents. When I woke my display up just now, I was presented with the Login window. So I thought my computer had restarted itself. I logged in and went to Console to see if I had any error messages. The odd thing is, there was no report of any kind of rebooting! So at first, I thought that Leopard had some kind of built-in auto-logout security feature if there was no user activity for two days. But then, I opened up Transmission and found that my torrents had stopped. So why would Leopard log me out if torrents were still running?? Does anyone know anything about this? When I look at my Console messages over the past couple of days, there are only two messages worth noting:

Another strange thing is, I cleared my console before I left on Saturday, and there is nothing before those two lines of code. Also, even if I were logged out by Leopard, wouldn't Transmission still be sitting there when I log back in? Am I wrong about that? I am so confused right now :\
