Cause
SQL Server Wire Protocol driver uses the sp_sproc_columns_100 system stored procedure to get the stored procedure parameter metadata requested via the SQLDescribeParam call.
The application is preparing the stored procedure call and then calling SQLDescribeParam every time the stored procedure is used.
Resolution
Modify the application to prepare, describe and bind the stored procedure parameters once, then execute multiple times, copying in different parameter values each time.
