I have the same problem here and this thread solved my issue …
Basically different thread in the same application send the same packet-type to a server with a blocking SendReceiveObject call … but the responses were messed up … one thread get the response pertinent to another one …
I found very strange that this is not working out of the box … very confusing for me.
Anyway marking the response with a unique SendingPacketType for every packet solved the issue … thanks again for this thread!!
