Bug Description

Binary package hint: cloud-init

cloud-init doesn't correctly cache data it crawls from the metadata service.

The result is each of the jobs ends up crawling the metadata service. That alone shouldn't be a terribly bad thing, but today I saw one of the requests hang. The metadata service probably isn't tested to be thread save. The result of this is that jobs will be delayed and or not run.

The exact problem I saw, was that cloud-config-misc was hung. When I looked at it with 'lsof -p 340', I saw the following:

cloud-ini 340 root 3u IPv4 7010 0t0 TCP domU-12-31-38-04-7E-77.compute-1.internal:33818->instance-data.ec2.internal:www (CLOSE_WAIT)
