Render going black with spectral rendering enabled

If I render the image with out the spectral rendering enabled it completes just fine, if I select spectral, It renders for about 25%ish give or take a little (600 iterations) then around half the image goes black, any ideas? Other than Chrome nothing else is running while I render.
