I have an Oracle 10g database for which OEM (and SQL Plus) are reporting seemingly incorrect space information about the flash recovery area.  This ocurred after I had an issue with excessive redo and was forced to remove my archive logs (RMAN > delete archivelog all;) and restart the database a couple of time.

Parameter db_recover_file_size_dest is set to 25G.  Currently the files on disk in the FRA occupy about 11.2 GB but OEM is reporting "Free Flash Recovery Area at 2.17 GB.  Additionally, OEM is reporting the following error instead of displaying the FRA usage chart on the Recovery Settings page:

Unhandled exception during generation of chart Flash Recovery Area Usage.  oracle.charts.types.ChartException: Chart Builder Error: setSeries(): slice value must be non-negative.

So it looks like, for whatever reason, the calculation of total and free space in the FRA is incorrect.  

Any ideas on how to fix this issue?
