Hi, I see what seems to be this same problem on my 8.10 server AMI's on EC2. They freeze predictably after a certain period of activity. I found that memory got below 35MB free when it froze and my 'top' listing showed kswapd with nice of -5 appearing 2nd on the process list. My server image has no swap defined. Hope this info helps.
