Race detected during closing of IPrintAsyncNotifyChannel.

This stop indicates that a notification arrived during a call to CloseChannel. If this condition occurs, it might be impossible for the consumer to correctly release the channel.

Parameter 1�-�IPrintAsyncNotifyChannel interface pointer.

Parameter 2�-�Thread ID of the member function called.

Parameter 3�-�Thread ID of callback event function.

Parameter 4�-�Not used.

Stop code: A027

This stop should not be encountered frequently. It can be prevented by always ensuring a listener is available before a bidirectional channel is created, or by ensuring that no listener can be started before attempting to close a channel that has already sent a notification but not received the callback.

Please report this stop to Microsoft.
