I keep running out of memory, I've never ever had this problem up until now.

I have 5 accounts running on one machine, the main is even in full graphics mode. I've been playing this way for about 2 months now and no issues at all.

Now every time i log each account in I run out of memory and crash all clients. The slaves are running at 250megs on average and main is at 500+ ?!? no addons and the settings have been switched to low. I just dont get what has changed all of a sudden to make me run outta memory? WTF?

Any ideas? I dont see anything unusual in task manager.
