Profiler Stops Updating on Change Level

Hi guys, I'm profiling is switching levels in a game I'm working on just now, and I suspect that when I switch levels there might be a memory leak. I'm profiling a build, not anything running in the Editor.

The first time the level changes (it's just reloading the same one repeatedly) my Total System Memory Usage jumps up and I start getting the "Skipping profile frame. Reciever can not keep up with the amount of data sent" warning spewing into my console constantly.

The second time the level changes the warning continues to spew into my build but the profiler stops running entirely - it is not moving/updating at all. I therefore can't tell anything about my memory usage from that point on.

Any ideas what could be causing this or how I could get round it? I've tried doubling the Profiler.maxNumberOfSamplesPerFrame but that made no difference.
