FIX: Commit Causes an Assertion and the SQL Server Program Stops Responding or Closes (319212)


The information in this article applies to:

  • Microsoft SQL Server 7.0
This article was previously published under Q319212
BUG #: 102436 (SQLBUG_70)

SYMPTOMS

If a SQL Server connection (system process ID [SPID]) performs a data definition language (DDL, for example, it modifies a database object's structure by creating an index or renaming an object) operation and the DDL operation modifies the data in a temp table in a single transaction while another SPID commits changes to a table, the first SPID may raise an assertion error while trying to commit. After the assertion occurs, a handled access violation occurs. In some cases, after the access violation occurs, the SQL Server service may stop responding. In other circumstances, an unhandled exception may follow the assertion and cause the SQL Server service to shut down.

This text is logged to the SQL Server error log: 
2001-07-30 01:20:08.38 kernel SQL Server Assertion: File: <xdesmgr.c>, line = 818 
Failed Assertion = 'xlockinfo.IsLockListEmpty ()' closexdes: lock list not empty.
2001-07-30 01:20:08.38 spid12 Error: 3624, Severity: 20, State: 1.
The line number in this example is from SQL Server 7.0 Service Pack 3 (SP3).
