great. One thought, it may be that the network connector is not requesting a sync send. It trys to respect the original client but in the case of a transacted client this may be a problem as messages are send async and batched at commit time.
Using a client side connection url parameter, jms.alwaysSyncSend=true would help validate if this is part of the problem as it would ensure each send is sync from the client.
