Consider the following scenario. In Microsoft SQL Server 2005, you try to use common language runtime (CLR) functions to load data. You do this by running a Transact-SQL job. This Transact-SQL job is started by SQL Server Agent. In this scenario, the job fails, and you receive the following error message: Additionally, the following messages are written to the SQL Server error log:

This problem occurs because CLR parallel threads are incorrectly shut down when you run parallel queries. Typically, this problem occurs when the following conditions are true:

• A correct shutdown occurs in the main thread, and subthreads have not exited. In this scenario, the subthreads will stop the main thread, and the CLR thread is ended.
• An exception is not managed when you try to enter an aborted CLR thread, and you are stopped on the stub.
