BUG #: 58327 (SQLBUG_70)
Stack dumps are diagnostic information that are used to troubleshoot problems. Stack dumps can occur when SQL Server encounters an exception or assertion, or explicitly when support engineers run certain diagnostics.
The generation of stack traces by SQL Server can result in a virtual byte memory leak. When SQL Server is installed on computers with 2Gb or more of physical RAM, specific errors indicating that virtual memory is low in the SQL Server process space can occur, depending on the frequency of the leak and the available virtual memory:
Two examples of these error messages are:
Error: 17802, Severity: 18, State: 3
Could not create server event thread.

Rename the SQLImage.dll and DBGHelp.dll files in the \BINN folder for the SQL Sever installation to different file names. If you are running on a Microsoft Windows 2000-based computer, this step is enough to avoid the problem.
If you are running on a Microsoft Windows NT 4.0-based computer, you also must replace IMAGEHLP.dll and DBGHelp.dll in %systemroot%\system32 with the copies of these files from Windows 2000.
Microsoft has confirmed this to be a problem in SQL Server 7.0. This problem has been corrected in U.S. Service Pack 3 for Microsoft SQL Server 7.0.For more information, click the following article number to view the article in the Microsoft Knowledge Base:
