I upgraded to 4GB RAM to try and avoid the crashes I was experiencing
after doing a looped recording.  I've not yet had any crashes upon
clicking the 'Stop' button, but now I've been seeing tracks disappearing
much more frequently.

The image here shows how I've recorded punch ranges inside of a loop
range.  While recording, I see regions being created on all 8 tracks.
When I clicked 'Stop', audio data vanished from the Audio 7 track on two
out of four occasions:

I then selected all of the regions and hit the 'Delete' key to try and
remove them.  The system suddenly became very unresponsive and I
launched 'top s' to find that Ardour was using 6562MB RAM and the figure
was increasing!

Upon killing Ardour the system returned to normal.
