Hi I have almost the same setup, even less memory (256Mb) and have no 
problem like that in "normal" situation. I have however notice a similar 
problem when using ardour but only when inserting some plugins and only 
when I insert these plugins pre-fader. It is a very strange (and not 
always repetitable) behaviour and I don't know the reason of it.
