The size of the Microsoft System Center Operations Manager 2007 Service Pack 1 (SP1) Data Warehouse database may grow if many event collection rules exist within management packs.

This problem occurs because the System Center Operations Manager 2007 SP1 Data Warehouse raw event tables are not groomed as expected when the data retention setting is reached for the Event dataset. Therefore, Event partitions (SQL tables that have names that resemble Event.Event_<guid>) remain indefinitely in the System Center Operations Manager 2007 SP1 Data Warehouse database.
