Memory problem

When I run the game engine and then stop it (ESC) I see that blender’s memory usage keeps accumulating every time i run the game engine. Then at some point it just crashes. Is there a way in blender to free memory? You can see it even with the default blender scene (just a cube).

Hmm…I have something similar.

when I model in blender, eventualy it starts to slow down after 10 min. But when I go in and out of the game engine, it all the sudden starts working fast again.

maybe its a memory leak?
