BUG #: 355451 (SHILOH_BUGS)
An ODBC application that uses the SQLPutData API may cause a leak of buffer pool memory with each invocation. This buffer pool memory cannot be reclaimed and over time may cause SQL Server to run out of buffer pool memory. This condition can cause the SQL Server program to stop responding (hang). One of the most visible symptoms of the problem is Error 17803 as seen in the SQL Server error log.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
SQL Server 2000
This problem was first corrected in Microsoft SQL Server 2000 Service Pack 2.
SQL Server 7.0
This problem was first corrected in Microsoft SQL Server 7.0 Service Pack 4.
In SQL Server 2000, each invocation of SQLPutData results in a leak of buffer pool memory of approximately 8 K. In SQL Server 7.0 the leak of buffer pool memory is approximately 272 bytes. The only way to reclaim the memory is to restart SQL Server.
It is important to note that although a 17803 error message that occurs when a user connects is a symptom of this problem, the error message can also occur in other circumstances outside of the scope of this problem.
