824684Under certain circumstances, a non-optimal query is generated to be used by the bts_FindSubscriptions stored procedure. In this scenario, the bts_FindSubscriptions stored procedure becomes very inefficient and consumes a larger than expected percentage of CPU cycles on the SQL Server-based server. In this scenario, the bts_FindSubscriptions stored procedure becomes a bottleneck for processing documents in BizTalk Server.
(http://support.microsoft.com/kb/824684/ )Description of the standard terminology that is used to describe Microsoft software updates

Use BizTalkMsgBoxDb SELECT TOP 5 COUNT(*) as count, uidPropID, vtValue FROM EqualsPredicates GROUP BY uidPropID, vtValue HAVING COUNT(*) > 5 ORDER BY count DESC
