FIX: When an ADO.NET-connected application uses the System.Data.SqlClient namespace, the application may experience high CPU use and may stop responding
On This Page
SYMPTOMS
When a Microsoft ADO.NET-connected application uses the
System.Data.SqlClient namespace, the application may experience high CPU use. Also, the application may stop responding.
This problem may occur if the following conditions are true:
- The ADO.NET-connected application is in a high-stress scenario.
- The ADO.NET-connected application has sent an attention signal to Microsoft SQL Server. (The attention signal is usually sent in response to a query time-out.)
- The client connection shuts down before it receives the acknowledgement of the attention signal from SQL Server.

Very often, it takes hours to solve a problem. Very often, you've looked high
and low, and have tried a lot of solutions. When you finally found it, chances
are, it was because someone else helped you. Here's your chance to give back.
Use our community feedback tool to let others know what worked for you and what
didn't.
Please also understand that the community feedback system is not warranted to be
correct, it's simply a system that we've built to let people try and help each
other. If something in a feedback response doesn't make sense to you, or you're
not comfortable making changes that the feedback talks about (like registry
edits), please consult a professional.
