Hi,
I found a question at the Q&A site which deals with circuits: URL:http://tor.stackexchange.com/q/492/88 The guy set up a Tor relay on its DSL connection. According to the Tor logs there are some low numbers of circuits open. From time to time this number jumps up (from 8--1 circuits to 700--850). Do you also see such numbers? What can be the reason for this jump?
