The Event Source Overview Sync RDD is improperly adding event information and causes large amounts of space to be consumed within the database (postgresql). To verify if this is the problem, check the size of the database files located at /var/opt/novell/sentinel/3rdparty/postgresql/database_rpt_files/PG_9.0_201008051/16394
For an updated report that can replace the deleted report, contact NTS for a new version that does not have a dependency upon the problem RDD. The new report takes advantage of existing RDDs without a problem.
In an upcoming release of Sentinel Core Solution Pack the problem will be fixed and you will simply need to import the fixed Solution Pack.
