SYMPTOMS
When you run an application that uses the Microsoft .NET Framework Data Provider for ODBC, you may receive an exception error message, and your application may stop responding.
CAUSE
If the ODBC data provider raises an exception, the ODBC manager may leak a SpinLock object in the common language runtime. This causes high CPU utilization because one or more threads are involved in an endless loop. This causes your application to stop responding.
RESOLUTION
A supported hotfix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Only apply it to systems that are experiencing this specific problem. This hotfix may receive additional testing. Therefore, if you are not severely affected by this problem, we recommend that you wait for the next Microsoft .NET ODBC data provider service pack that contains this hotfix.
