Hi cj,
Sorry for delaying this response due to a sick leave.
If your SQL connections are closed and disposed as soon as they are no
longer needed, they won't be leaked. For the COM objects or references, you
may check if they provide a method to release themselves. Dispose method is
just a .NET class who implemented IDispose interface, however for those
unmanaged objects, if they were not wrapped in a .NET class which
implemented IDispose interface, you need to use their self-provided release
function to release themselves.
From the perfmon monitor result, we can see that this is a unmanged
resources leakage issue. The managed resources were controlled very well in
your application. I do not know what the COM component you used was, but
there might be another possible reason, if the COM component itself has
memory leaks, it is hard for you to correct it in your .NET application.
I recommend that you work with your COM developers to identify which COM
objects and references need to be released in what way.
Hope this helps. If you have any other questions or concerns, please feel
free to post back. I am glad to work with you for further assistance.
Best regards,
Charles Wang
