I looked through the old log files and found the following memory messages:

To me it looks like an attacker that ramped up over a 6 hour period and
then stopped building new circuits. Since the tor process still uses all
available memory (more than 24 hours later) I guess the attacker still
holds some circuits open. To what end I can't understand. He failed to
crash the relay but wants to occupy my RAM? :)
