BUG #: 14492 (Plato7x)



SYMPTOMS
If the lazy aggregation process is suspended multiple times for the same partition because of other processing operations in Microsoft SQL Server 2000 Analysis Services, the following Error event may be logged in the event log: Event Type: Error

Event Source: MSSQLServerOLAPService

Event Category: Server

Event ID: 128

Date:

Time:

User: N/A

Computer:

Description:

Error during lazy aggregation of partition  in cube  :



CAUSE
This problem occurs because the counter for the number times that the lazy aggregation process is suspended for the same partition is not reset. This counter is not reset when the lazy aggregation process cannot finish because of a cancel request that is generated by another process on the server.

Analysis Services uses background threads to rebuild flexible aggregations for a partition. This occurs after an incremental update to a changing dimension caused the aggregation to be dropped. The server keeps an internal count of the number of times that the lazy aggregation thread tries to process aggregations for a partition. By default, the lazy aggregation thread tries to process the missing aggregations for a partition three times. Then, the lazy aggregation thread reports an error for the aggregation-building process and marks the partition as being unable to be indexed.
