Error 8908
Severity Level 16
Message Text
Table error: Database ID %d, object ID %d, index ID %d. Chain linkage mismatch. %S_PGID->next = %S_PGID, but %S_PGID->prev = %S_PGID.
Explanation
This error occurs when Microsoft® SQL Server™ detects an inconsistency in the page linkage of one of the page chains associated with a table, for example, when a page's next pointer points to a page whose previous pointer points back to a different page. There is one doubly-linked page chain for the table data as well as one for each index level.
Important This is a serious error and must be corrected immediately.
If DBCC statements detect this error during run-time processing, error 605 will also occur.
Action
Determine which table is corrupt by examining the current page in the error message. Execute DBCC CHECKDB without a repair clause to determine the extent of the corruption. Then, execute DBCC CHECKDB with the appropriate repair clause to repair the corruption. If the page is associated with an index, it is sometimes possible to resolve the problem by dropping the index. In most cases, you must recover the database from a known clean backup.
If the error involves an index page, use the REPAIR_REBUILD clause. If the error involves a data page, it may be necessary to use the REPAIR_ALLOW_DATA_LOSS clause. In the likely event that you cannot allow the loss of data, you will need to restore from a known clean backup. If the problem persists, contact your primary support provider. Have the output from DBCC CHECKDB available for review.
Important If executing DBCC CHECKDB with one of the repair clauses does not correct the index problem or if you are unsure what effect DBCC CHECKDB with a repair clause has on your data, contact your primary support provider.
You should also examine your operating-system error log file, in addition to the SQL Server error log, to determine if hardware errors might have caused the corruption.
If the problem persists, contact your primary support provider. Have the output from the DBCC CHECKDB statement available for review.
