I am running a data driven unit test and I am receiving the following error:

The connection to the controller was lost.

Other detail from the test result summary:
Test run name:     1  rcollet@RCOLLET 2006-07-20 14:13:39

The test code does function properly when used with a small data set.  As
the data set size is increased, I encounter the error.

The test is being run in run mode (not debug)

Test purpose:
Compare input and output data exported from an existing system being
migrated to .NET to insure the .NET version creates the same output from the
object.

Test method:
Read input and expected data from a .csv file, place input data into object
properties, place expected properties into another object instance, execute
object method which modifies its properties, use object's equals method to
determine if actual meets expected results.

Test Code:

   <DataSource("System.Data.OleDb", "Provider=Microsoft.Jet.OLEDB.4.0;Data
