App isn't running the expected Ruby version

We have checks to ensure that the version of Ruby the application is using is the same as the version specified in its .ruby-version file.

The standard reload that happens when an application is deployed is not enough to move between Ruby versions, so the application will continue to run under the old version.

A hard restart of the application is required before the application will run under the new version. You can do this by running the app:hard_restart deploy task within the 'Deploy App' job in Jenkins.
