BUG #: 351363 (Shiloh_bugs)



SYMPTOMS
Calling OLE Automation support stored procedures, namely sp_OAMethod, sp_OAGetProperty, and sp_OASetProperty, leak a small amount of memory in the OLE Automation Object operation DLL (Odsole70.dll) file. This may cause the following errors to be reported in the SQL Server error log:

2000-11-27 11:22:59.87 server SQL Server could not spawn process_loginread thread.

2000-11-27 11:25:09.42 server SQL Server could not spawn process_loginread thread.

Sometimes, the following error has also been reported:

2000-11-27 11:55:06.09 spid431 WARNING: Failed to reserve contiguous memory of Size= 65536.

2000-11-27 11:55:06.09 spid1714 WARNING: Failed to reserve contiguous memory of Size= 65536.

In very rare situations, this may also result in the termination of the SQL Server process. Note that the preceding symptoms usually occur a long time after the server was started and only when the OLE Automation stored procedures are used frequently.



CAUSE
When calling any of the sp_OA procedures, a string that was allocated was not freed, leaking few bytes on each call. The size of the leak is not fixed and is dependent on the string.



RESOLUTION
To resolve this problem, obtain the latest service pack for Microsoft SQL Server 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
