症狀
假設您在 Microsoft SQL Server 2012、2014 或 2016 中將資料庫的目標復原時間設定為非零值。 如果判斷提示在檢查點程序期間發生,判斷提示會導致資料庫上的租用逾時,且您會收到下列傾印檔案:
date time spid14s Error: 17066, Severity: 16, State: 1.
date time spid14s SQL Server Assertion: File: <recoveryunit.cpp>, line=7849 Failed Assertion = 'm_ReducedDataSlice <= MaxReducedDataSlice'. 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.
date time spid14s Error: 3624, Severity: 20, State: 1.
date time spid14s A system assertion check has failed. Check the SQL Server error log for details. Typically, an assertion failure is caused by a software bug or data corruption. To check for database corruption, consider running DBCC CHECKDB. If you agreed to send dumps to Microsoft during setup, a mini dump will be sent to Microsoft. An update might be available from Microsoft in the latest Service Pack or in a Hotfix from Technical Support.
date time spid14s Error: 18400, Severity: 16, State: 1.
date time spid14s The background checkpoint thread has encountered an unrecoverable error. The checkpoint process is terminating so that the thread can clean up its resources. This is an informational message only. No user action is required.
