Has anyone got any further suggestions as to what might be causing this 
problem?

It's a rather serious issue -- Ardour is not much use to me if I can't 
create/delete/re-route tracks without it disconnecting from Jack. I 
realise it might not be a problem with Ardour that's causing it, but 
it's still a major show-stopper.

Thanks again
