When you use the NOLOCK hint, you may experience transient 8908 errors in the SQL Server error log on tables that experience high volumes of SQL Server activities.

The error message that occurs is:
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.
An error may occur when you use the NOLOCK optimizer hint to query tables in the database. There is a small timing window during page splits in conjunction with parallel nolock scans and concurrent updates that can generate transient 8908 messages.
To ensure that the database is free of corruption, run a DBCC CHECKDB statement, preferably in single user mode, against the database. If DBCC CHECKDB returns no error, you can be certain that the database is free of corruption.
