Hi Rob. I call connection.setCopyMessageOnSend(false) on the producer and consumer connection objects, and yes, the producer and consumers all use the vm transport.
See my second post in this thread for sample code demonstrating the problem. (Actually, I just noticed that in that code I have "copyOnSend" set to true for the consumers, but I've run tests with it set to false on consumers, too.) rajdavies wrote: > > Hi Ryan, > > how are you setting copyMessageOnSend - and are the consumers using > vm://transport too ? > -- View this message in context: http://www.nabble.com/VM-transport-not-using-pass-by-reference-tp17442075s2354p17527119.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
