AWS instances at 100% because of leap second bug in Linux

July 1, 2015

I woke up to see two of my instances, running in AWS Singapore, at 100% and unresponsive. Rebooting also did not help. They had to be killed. Thankfully AWS had documented this on their support page:

“Additionally, some customers have reported continued connectivity issues for some of their instances. We have seen with these reported issues that this has been caused by a leap second bug within the instance operating system, which results in 100% CPU utilization. We recommend rebooting the instance via the EC2 Management Console or API, or resetting the operating system time to resolve the issue. For further information see:
