SFEE log files are not purged automatically. Maintain the SFEE disk footprint by configuring your log retention policy.
SFEE, if left unattended, will continue to grow in its disk 'footprint'. A significant portion of this growth is because the log files are not purged automatically. It was determined that no single log retention policy would suit all customers, so we opted to keep all logs and let the customer determine the rate/criteria for deletion.
For detailed information including which logs to delete and a sample script to help you maintain the files regularly, see Disk Usage.
