When closing a position using the 32 bit C++ COM Wrapper version 1.0.1.47, I am receiving an error message that says the server threw an exception of (RPC_E_SERVERFAULT)

Here is the entire error message when closing a position of ESU20

The server threw an exception. (Exception from HRESULT: 0x80010105 (RPC_E_SERVERFAULT)) at System.RuntimeType.ForwardCallToInvokeMember(String memberName, BindingFlags flags, Object target, Int32[] aWrapperTypes, MessageData& msgData)

Just in case, can you comment out everything that your listener for AvgPositionChanged does, and see if the exception still occurs?

I'm very sorry I didn't see this come in, I must not have subscribed to the topic.

After commenting everything out in the AvgPositionChanged the error message does not occur.

Judging by the call stack, and the fact that the error no longer happens when your AvgPositionChanged handler is commented out.. I think the problem is in that handler.

Something in that function is throwing an exception.
