Symptoms

When you bulk insert data into a table from multiple connections in an instance of Microsoft SQL Server 2016, an assertion that resembles the following is logged in the SQL Server error log. Additionally, a dump file is generated.

SQL Server Assertion: File:< pageref.cpp>, line=LineNumber Failed Assertion = 'IS_OFF (BUF_MINLOGGED, m_buf->bstat) || pageModifyType != PageModifyType_Contents || GetPagePtr ()->IsTextPage ()'. 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.
