I've never seen this before. Came home to find BI using 38GB of memory...

PC was lethargic, and I was getting an "out of memory" error on my scanning software that runs in the background of the BI machine.
This was running 5.5.9.5. My system has 48GB of RAM.
BI is running as an app, not as a service, and I did have the console on full screen - something I normally never do.
Upon closing the console, the memory returned to normal. I've restarted the console, and so far it's staying around 8-10GB.
Any ideas what could be causing the memory to runaway like this?
