I'm seeing similar problems on vine at the moment, last months uptime was 100%, this month I've had 6 outages with the downtime down to 99.304%, while not the end of the world, it would appear someone is running a dodgy script on vine of late, a few days ago I went and checked the load averages because my sites were down and they were up around 300. Of course the server crashed soon after. This has occured a few times in the last week.
Hopefully it isn't a sign of things to come since the cpu restrictions have been lifted, while I think most people won't go nuts with scripts there is always someone that will try to take advantage of the situation.
