Upgrade an EC2 Instance from 2.6.16 to 2.6.18

I’ve been using the Amazon Elastic Computing Cloud (EC2) for running our web servers at NetCrafters for almost a year now. It’s been an amazing experience and I’ve kept a detailed account of many of the lessons learned.
Amazon Web ServicesThe most recent challenge came when our servers just started locking-up for no reason. The sites would still be responding so we knew the LAMP stack was still limping along, but they were completely unresponsive via SSH. The only way to regain control was to issue a reboot through the Amazon API command line tools. Even this would sometimes take two or three times before the server would cycle.
