Hello !

We have an OPC Server Application and 3 OPC Client Application connected to the OPC Server. When i kill a Task from an OPC Client application, then in a serveral time the OPC Server application hangs sometime for 40 to 60 seconds. When this happens the OPC Client connection from the other client throw an error with the message “Systemaufruf ist fehlgeschlagen.No more info available” The the client try to reconnect to the server, then the application crash with “Access violation” in “RPCRT4.NdrStubCall2”

Do you know the problem ?

I try following:
I remove the client from the server with OPCProvider.RemoveClient(). The OPCProvider.ClientCount goes from 3 to 2, but in a serveral time the application hangs for 40 to 60.

Does DCOM do anything in the background.

Do you have any hints ?

This does not sound familiar. “RPCRT4.NdrStubCall2” is also unknown to us – is it related to your own application? Maybe it is referring to a client connection that was removed?

Is there a good reason that you need to kill the client or are you just experimenting what happens, if you do so?
