I have developed OPC clients in c++ using OPC interfaces.

When OPC client is disconnected to OPC Server, IOPCServer interface is released on my code. However, Releasing IOPCServer takes some times. To reduce to the time, I'm trying not to release IOPCServer and just fill in with null. What if IOPCServer is not released? Is there any way to reduce release time?

The delay may be because of a deadlock created by a callback that happens to be occurring before you release the server object.

I suggest you remove any connection points you have set up before you release the server.
