Mu-so network stack and BBC HD radio

Anyone getting crashes on the Mu-So network stack when playing BBC HD radio after a few minutes?

I loose Bluetooth and the ethernet when this happens. The 'fix' is to walk up to the Mu-so (as the Naim App cant see the Mu-So anymore) and change the input to a non-networked input (anaulogue/fiber et) then it all kicks back into life again (or powercycle the beast).

Any other feed including the SD BBC works fine
