Sounds very familiar, what's the size of your FDB like? I don't remember
the exact details, but if it gets full then you'll see spikes like that
whilst it tries to find some old entries to throw out to make room for
new ones.

Don't remember it ever occurring regularly every 30 minutes though. I
guess perhaps there is something else on the network that runs once
every 30 minutes and causes a lot of new FDB entries to be created?
