[tor-bugs] #7799 [Tor]: Tor seems to build+timeout circuits for hours when offline/idle (was: remove (or scale down a level) obnoxious "No circuits are opened. Relaxed timeout for a circuit with channel state open to 60000ms. However, it appears the circuit has timed out anyway. 0 guards are live." message)

New description:

 Since I've upgraded to .7-alpha I am having my log file filled with the
 above message, which is generated a couple of times a *second*!
 \
 I have, so far, accumulated over 14,000 lines with this crap, which seems
 to be generated when tor was left idle (unused) overnight. I had to
 increase my log level (to "warn") in order to get rid of it temporarily,
 but that isn't good enough, since I cannot see my other (very useful)
 messages appearing at that level (notice) without having my log filled
 rapidly.

 Here's the logline from the original bug title:
 "No circuits are opened. Relaxed timeout for a circuit with channel state
 open to 60000ms. However, it appears the circuit has timed out anyway. 0
 guards are live."

Comment(by mikeperry):

 Hrmm.. The bug submitter seems to be hitting the rageahol a little too
 hard this holiday season. A little investigation reveals a few things are
 incorrect in the bug report's description.

 First: The reported logline is info level, not notice. It's possible that
 the notice line was *also* triggered, but that's not immediately clear
 based on the situation description.

 Second: I strongly suspect that Tor wasn't idle, but was actually
 disconnected from the network. This is probably the real bug+repro case
 here.

 So the remaining question is: Does this actually happen for idle clients
 as reported, or do they have to be disconnected from the network in
 addition/instead?
