What is the best way to test if we are impacted by this bug? We run the following image on c1.xlarge's and see nodes die about every 1-2 days now under a continuous >50% CPU load. The nodes will fail the EC2 instance status check and all monitoring daemons on the node will stop reporting.

However, there is no backtrace or any information in the logs after a reboot to diagnose what failed. Is there a change required to dump the stacktraces seen above in order to tell if we are impacted by this same bug?
