Description

When the Github Org Folder Scan runs and tries to clean up old branch and PR builds, we see errors like ".nfsXXXXX: Device or Resource Busy".  See stack trace below:

When I go look at the open files on the Jenkins java process, I see a bunch of .nfs files which appear to be all related to EC2 instances managed by the EC2 Plugin.
