Have you applied the ADO Update 2 from Borland to your Delphi 5?

This is with Delphi 5 and SQL Server 2000. We have a thread which updates a SQL Server database via a stored procedure when monitored data in the application is changed or added. The thread instantiates its own TADOConnection and a TADOStoredProc. As changed data is detected the TADOStoredproc's parameters are updated and the ExecProc method called. The purpose of the thread is to pipeline database updates from the 20 - 500+ execution threads handling client processes. On one machine (Windows Server 2000) the second time the ExecProc method is called the application vanishes - no errors, no Dr Watson. On all other machines we run it on the application behaves beautifully. The failure occurs with only 12 active threads, so it does not seem to be load related as the application happily runs in the real world with over 1500 threads. The fix has been to instantiate the TADOStoredProc for every database update and then free it. While this works it is not elegant and as it may run up to 100 times a second the inefficiency is a problem. Any ideas what may be the cause, either from the ADO components or the Windows 200 Server environment?
