This morning I got my first Tor traffic flood since upgrading to 2.4.x. Logs didn't say anything about not being able to handle the amount of circuit creation requests, but it showed a 200x increase in active TAP circuits (~400k/hour) and the traffic pattern is the same: Advertising 100kb bandwidth, but slammed with ~2Mb traffic.
When I saw it, I checked my relay's flags, and it has the stable flag, and has been tagged stable for at least 3 days. It's been up for 7 days. I would love to contribute data to help correlate w/ your findings Gordon. Any metrics or logs that would be particularly helpful? I currently use NTop to measure traffic, but it's not very granular. I also currently don't use any iptables rules to throttle, but am happy to experiment with that if you want me to try out any particular configurations.
