DBCC2_PRE_CHECKS_CHAIN_LINKAGE_MISMATCH

Message

Text

System table pre-checks: Object ID O_ID has chain linkage mismatch. P_ID1->next =

P_ID2, but P_ID2->prev = P_ID3. Check statement terminated because of an irreparable

error.

The first phase of a DBCC CHECKDB is to do primitive checks on the data pages of critical

system tables. If any errors are found, they cannot be repaired; therefore, the DBCC CHECKDB

terminates immediately.

The next page pointer of page

P_ID1

points to page

P_ID2

; however, the previous page pointer

of page

P_ID2

points to page

P_ID3

but not back to page

P_ID1

, as it should.

Run hardware diagnostics and correct any problems. Also examine the Microsoft Windows

system and application logs and the SQL Server error log to see whether the error occurred as

the result of hardware failure. Fix any hardware-related problems that are contained in the logs.
