I have very, very few users.

I was scrapping some data today but that's usually not a problem. I've attached a screenshot of my instance stats.

Everything hasenter image description here normalized and the instance is still hanging. Do I have any hope here?

Which OS are you using ? – Iain May 25 '11 at 20:39
Using Ubuntu 10.4 – Ben May 25 '11 at 20:41
When it hangs can you still use ssh to access it ? If you can what does top have to say ? – Iain May 25 '11 at 20:47
I can't ssh into the instance, which is clearly not a good sign – Ben May 25 '11 at 20:53
Try restarting it, if that doesn't work, detach the EBS-block and start a new instance. Don't get attached to your EC2-instance :-) – Bart De Vos May 25 '11 at 20:58

Amazon EC2 instances should be thought of as temporary, we have about 100 running and about 10% die every week, we just kill them off and start again. Just create a new instance from the EBS image (You created an EBS image right? ;) ).

At first I thought this was a bit odd for so many instances to fail on such a regular basis but I contacted AWS support and they said pretty much what I said above. Infact I don't think I've ever had an instance running for longer than a month without it failing (Although we do hammer all our instances, they're on 100% CPU pretty-much all the time)

This is really a useful point of view. I felt like a tool for blowing up an instance without any real traffic. Now I know that it just happens sometimes. Thanks – Ben May 25 '11 at 22:34
