A few people have reported increased RAM usage recently, on and off list.
It may be the next stage of the extra load.
It even happens on relays with the destroy cell fix.

On my machine, Tor used too much RAM and started swapping.
Please use the advice in previous threads to reduce connections and RAM.

If it keeps going, we will analyse the traffic and make code changes.
