This is the second time it happens to me.
My aws server, simply dies, no notifications, I can't ssh to it, nothing.
Only after I restart it, I can ssh and everything goes back to normal.
I check there faq page: http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/TroubleshootingInstances.html
and simply nothing there, I look at my logs as I attached below, and still nothing... any ideas?
