## Symptoms

- * Free space on the Gaia root (/) partition decreases significantly on a Security Gateway that runs Threat Extraction and Mail Transfer Agent (MTA).
* The Threat Extraction SQLite database file becomes very large: `$FWDIR/conf/scrub_db.sqlite`

## Cause

The Security Gateway processes a very high volume of files. The traffic includes automated emails and image-heavy emails. Many messages contain multiple embedded image files.  
These files cause frequent inserts and updates in the Threat Extraction database.  

Under the high-volume workload, the database cleanup process cannot delete expired records fast enough. The cleanup uses **DELETE** operations that require full table scans, which creates a cleanup backlog.  
As a result, `$FWDIR/conf/scrub_db.sqlite` continues to grow despite the configured retention settings.
