There are no actual limits. JBM will start to page messages to the database once a certain threshold is reached. These are read back in to memory when a queue dips below a certain limit.

I'm not sure why that would happen, one thing i would say is that sending messages as fast as you can will flood the server. Try adding some flow control and see if that makes a dsifference, say, only send n messages every second.
