It is making a SendNotifyMessage() call to synchronize the operation. So if you have a busy application it may take some time before the operation gets done. Releasing the resources of the client obviously may also take some time.

Hello Jouni

Thank you !

Does the OPC Server run in a seperate Thread ?

If yes, why does the application hangs ?

The client calls are coming in separate threads, but main data handling is in the main thread. I cannot say exactly why it hangs for a while. Maybe the internal COM stuff has also something to do with it.
