Sorry I don't really know much about it. In my case it was an application that used the http server dll from OpenSim and served probably 40-60 simultaneous requests. Mono was defaulting to 25 threads per cpu but I changed it to 75 and I stopped having download problems. This was on a 4-core machine.
I would guess if you are using 150 and seeing problems that a good place to start might be somewhere around 450-600 and see what happens.
