徵狀
假設您在 Microsoft SQL Server 2012、2014或2016中，將資料庫的 目標恢復時間 設為非零值。 如果在檢查點處理期間發生斷言，則斷言會在資料庫上產生租約超時，而且您會收到下列 dump 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.
