But that was a good decade ago. No issues now (for me).
But still I like to run a recursive resolver locally (rather than using a well known public resolver), and part of the problem is that I was getting SERVFAIL responses due to bits of the lookup getting dropped or taking too long (high latency VPN). So unbound fixes that, for rtorrent as well as other software running on the same machine. But maybe next time I visit that aspect of my setup, I'll look into making a Nix derivation for rtorrent with c-ares.
Edit: Also consider ruTorrent for a friendlier interface.
I'm seriously confused. What are you referring to?
It could have something to do with me having delay=5 in my profile settings? (This setting makes it so it takes 5 minutes for a comment to show up publicly, in case one wants to reconsider)
(I edited this comment based on investigation I did while this comment was in its delay period)
