Why Am I Seeing 'Permission Denied' Errors with a File or Directory in Ansible Tower?

Issue

A failure occurs in Ansible Tower installation, UI access, or a job run, with an error that indicates a failure to open a file, write a file, create a file or directory, or stat a file or directory on the local filesystem, and includes a message like 'permission denied'. The behavior may appear to be intermittent as it may affect only a subset of the nodes in a Tower cluster.
