Microsoft distributes Microsoft SQL Server 2008 R2 fixes as one downloadable file. Because the fixes are cumulative, each new release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2008 R2 fix release.
In Microsoft SQL Server 2008 R2, a database is marked as suspect when you try to recover the database. Additionally, the following assertion error is logged in the SQL Server 2008 R2 Errorlog file:
Note When this issue occurs, you have to restore the database from a backup to recover from the issue.
<Date> <Time> <SPID> Error: 17066, Severity: 16, State: 1.
<Date> <Time> <SPID> SQL Server Assertion: File: <page.cpp>, line=4953 Failed Assertion = 'm_freeCnt + emptySlots * sizeof (Slot) >= spaceNeeded'. This error may be timing-related. If the error persists after rerunning the statement, use DBCC CHECKDB to check the database for structural integrity, or restart the server to ensure in-memory data structures are not corrupted.
This issue occurs because a page may not have sufficient space when you recover a database.
Any thread that is involved in an Online Index Rebuild operation or a Shrink Database operation can compress a new page. If the page has insufficient space, the assertion error occurs.
