Verify TOSS 5 allocates a sufficient audit_backlog_limit to capture processes that start prior to the audit daemon using the following command:

$ sudo grubby --info=ALL | grep args | grep -v 'audit_backlog_limit=8192'

If the command returns any outputs, and audit_backlog_limit is less than "8192", this is a finding.
