Outbound circuit has 1500 cells in its queue
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hello. My new relay, 6B24AB532979E56A956A4F5EE23CC0B4AA17FA81, is experiencing somewhat higher inbound traffic than outbound. It doesn't appear to be the attack from what I can tell (there is no BEGIN_DIR flood), but it's causing the log to be spammed with "Outbound circuit has 1500 cells in its queue, maximum allowed is 1500. Closing circuit for safety reasons." every few seconds when ProtocolWarnings is enabled in the torrc. Average inbound traffic is 433 KiB/s but average outbound is 329 KiB/s. It's a new relay so some fluctuation is to be expected, but not this. The relay's network has plenty of spare bandwidth and there's no signs of traffic shaping. What could be causing this?

Since the upgrade I've noticed that one of my established relays has consistently 2 to 3 times more download than upload. On 31/10/26 11:26, forest via tor-relays wrote:

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Apparently _all_ my low-performance relays are experiencing this, not only my newest. The higher-performance relays show the cell drop message occasionally, but there's no asymmetric bandwidth that I can see. If there is, it's drowned out by the higher bandwidth usage. Is this another attack? A regression? This started occurring as soon as I upgraded to 0.4.9.15. CPU usage and network usage is otherwise normal. I'd be happy to provide debug logs to a dev if that would be helpful.
