Check out my new course Learn you some Lambda best practice for great good! and learn the best practices for performance, cost, security, resilience, observability and scalability.
Since migrating to Windows Server 2008 Datacenter for our Amazon EC2 instances I have noticed on many occasions that when a new instance is starting up RAC agent will cause the CPU to spike up to 100% for a good half an hour, at times the CPU spike never comes down and effectively renders the instance unusable..
After some digging around, I found this article which tells you how to disable the RAC agent:
In case the link stops working in the future, here’s the 4 steps you need to do:
1. go to Control Panel –> Administrative Tools –> Computer Management
2. navigate to System Tools –> Task Scheduler –> Task Scheduler Library –> Microsoft –> Windows –> RAC
3. right click RAC, select View –> Show Hidden Tasks
4. right click on the displayed task, and select Disable
