But sbws sets `__DisablePredictedCircuits 1` after bootstrapping, so sbws' tor only has its 3-hop circuits from when it bootstraps. When they expire, there are no more 3-hop circuits, so tor stops opening circuits. -- Ticket URL: <https://trac.torproject.org/projects/tor/ticket/28639#comment:18> Tor Bug Tracker & Wiki <https://trac.torproject.org/> The Tor Project: anonymity online
