In this case I agree with Anoop, even with the measures I have in place [0] I still occasionally bump into the original issue as well. So if it wasn't for Anoop, I'd start complaining sooner or later anyway :)

That would be definitely ideal, but it looks like only C9S AMIs are updated regularly, not quite sure why it's not the case for C8S as well.
