[tor-relays] Accounting limits seem to cause permanent hibernation

[Manuel Wiesinger]

Hello everyone,

I configured an accounting limit on my tor relay. 1-2 days after restarting the tor service the relay seems to go into permanent hibernation. Once I restart the service traffic is sent and received as expected, however after 1-2 days it seems to go into permanent hibernation again until I restart the service. The longest hibernation period was for about three month(!).

My configuration:

Tor 0.4.1.6, on FreeBSD 12.1. (nothing else running on the machine)

My relevant settings:

AccountingMax 128 GBytes
AccountingStart day 00:00

RelayBandwidthRate 2560 KBytes
RelayBandwidthBurst 5120 KBytes

Logs since the last restart: https://pastebin.com/wk04zDC8

Metrics: https://metrics.torproject.org/rs.html#details/A3BB86337E003A2668E016466EA3AAA6222E50A8
(The peeks in the graphs match the times when I manually restarted the service)

Since I experience this 'permanent hibernation' since at least last August, I wonder if it's expected behavior, e.g., caused by the small limit of 128 GB per day, or if it's a bug (possibly related to this one: https://lists.torproject.org/pipermail/tor-relays/2019-October/017862.html ?).

Best,
Manuel
