Comment (by arma):

 Replying to [ticket:24973 asn]:
 > Consider a Tor that starts up with 10 HSes configured(many of those Tors
 exist); it will easily attempt to make hundreds of circuits within
 seconds.

 You can see one of those Tors in action (probably with more than 10 HSes)
 at #24897:
 {{{
 Jan 20 16:33:30.000 [notice] We'd like to launch a circuit to handle a
 connection, but we already have 128 general-purpose client circuits
 pending. Waiting until some finish. [1808313 similar message(s) suppressed
 in last 600 seconds]
