Comment (by cstest):
There were aprox. 4000 lines of "No valid circuit build time data out of
1000 times, 3 modes".
Every couple of mins script was sending hup signal to tor and in log file
there are just 3 lines repeating:
{{{
Received reload signal (hup). Reloading config and resetting internal
state.
Read configuration file ...........
Tor 0.3.3.9 (git-ca1a436fa8e53a32) opening log file.
}}}
And sometime this appears in random order:
{{{
Your network connection speed appears to have changed. Resetting timeout
to 60s after 18 timeouts and 143 buildtimes.
}}}
but above line could be related to single v2 hidden service running. Then
almost 5 hours later new lines began to appear (hundreds probably due to
large number of v3 domains in torrc):
{{{
Failed to launch rendezvous circuit to
$835BDF974D1B6A324C15C48A95D49605AAAB51C1~ at ....
Giving up on launching a rendezvous circuit to

service v3onion....................

}}}
and occasionaly
{{{
Extremely large value for circuit build timeout: 123s. Assuming clock
jump. Purpose 14 (Measuring circuit timeout)
Couldn't relaunch rendezvous circuit to
'$0299F268FCA9D55CD157976D39AE92B4B.........
}}}
Single active v2 domain was working fine but not a single one v3. After
reloading tor, v3 domains started to work fine (nothing else have been
changed).
Have not found any "No circuits are opened" lines. At start, v3 domains
worked fine for several hours.
