Comment (by dgoulet):
Considering 10 intro points (maximum for v2), a service is allowed to
launch `((10 + 2) * 2)` (see rend_max_intro_circs_per_period()) intro
points in a 300 seconds window (5 min).
I expect that some of the intro points failed to establish properly (maybe
due to the ongoing load on the network?) and then you hit the mark. Some
INFO log would confirm that or help out greatly understand what is
happening then?
For the ~50 TIME_WAIT ... with that amount it is due to network problems
in some ways, most likely to the relays you are connecting to? That is the
FIN or final ACK got lost and the connection was stucked there. I would be
surprised that tor never close() those as at least the other side would
have?
