Ticket 50153 - Increase default max logs
    
    Bug Description:  The errors & audit logs default to max number of logs to 1.
                      This prevents the max log size rotation policy from working.
                      This is documented in the docs, but the problem is that this
                      can allow the server to fill up the FS on /var under certain
                      conditions.
    
    Fix Description:  Change the default max number of logs to "2".  This is still
                      a small value, and it allows the rotation policy to be effective.
