You need to divide and conquer. If the switch has nothing connected
to it in the loft, do you still see this behaviour? If not, try
adding one device at a time until you detect the "faulty" device.
This may provide further insight.
One possibility is that you have a duplicated IP address on your
network, although I'd expect that to manifest itself through random
broken connections rather than huge bursts of activity.
