Details

The audit service _MUST_ be configured to notify the system administrator when the amount of free disk space remaining reaches an organization defined value.

Solution

Run the following bash code

/usr/bin/sed -i.bak 's/.*minfree.*/minfree:25/' /etc/security/audit_control; /usr/sbin/audit -s
