Hi - no problem / thanks for the reply...

I'll give the above ago - part of the problem is not knowing which VM is 
going to die (there are quite a few) - the second part, is the waiting 
game...

Well, I'll get back to you when it happens again (personally - I hope it 
doesn't happen again) - but at least I know it's not quite as much of a 
dead end as I feared debug wise.

If this does happen again - and I'm able, is there any point in doing a 
snapshot + memory of the VM? (which is about the only thing I could think 
of - not knowing about the watchdog stuff).
