Agent leaks sockets to AWS S3

[cavaliercoder]

Occasionally, the CodeDeploy Agent leaks a socket when connecting to S3 to download application bundles. This is evident via call to netstat:

$ netstat -tp4
Active Internet connections (w/o servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name
tcp       54      0 ip-172-21-67-210.:53248 s3-ap-southeast-2:https CLOSE_WAIT  4953/codedeploy-age
...

This happens on a number of our Centos 7.2.1511 x86_64 instances on AWS EC2. Package details:

We had a similar issue in applications using the AWS SDK for Javascript (I understand this is written in Ruby). For reference, the issue was addressed, we think (please confirm) in v2.50.0.

Thanks for bringing this to our attention. We're using the ruby aws sdk for S3 so we're simply doing whatever that one does. Is v2.50.0 the version of the AWS SDK that you're referring to where this was fixed?

[cavaliercoder]

We understand a similar issue was resolved in the AWS SDK for Javascript somewhere around v2.50.0. Perhaps this issue is best addressed by the Ruby SDK team?
