One of the ones i came across was the I/O Access Mode and Data Compression settings to improve performance. Check that compression settings are still present.
In EAS, expand the application and database. Right-click on the database > Edit > Properties > Storage tab. Check that your "Data compression" is not set to "No compression" and that "Pending I/O access mode" is set to "Buffered I/O".
Sometimes the compression setting can revert to "no compression", causing the rapid growth of the data files on disk.
