I see. I'm trying to stay on 0.2.9.x since that is considered the "long-term support" release. This is a fallback directory mirror which I'd like to keep as stable as possible. apt wants to upgrade straight to 0.3.1.7 (from the repo at http://deb.torproject.org/torproject.org). I will see if I can install 0.2.9.12 from the repo instead, or perhaps install the package manually (or perhaps give up and switch to 0.3.1.7).

I think Tor LTS / 0.2.9 is in Debian stable:

http://deb.torproject.org/torproject.org/dists/stable/

I've opened a ticket to add LTS to the Debian repository instructions:


I wouldn't recommend upgrading to 0.3.0 or later, there are stability issues
on some clients, and maybe relays.

Could be. It's just simple iptables on the node, and I've tried to follow best practices for the sysctl and ulimit tweaks, but I don't really know what's going on upstream with the provider. It's a little odd that this is only a recent problem, as the node has been up for 700+ days and aside from kernel upgrades, there's no recent changes. Maybe it's just busier than usual now. I'll keep digging. Thanks for the feedback!

There's a bug in 0.3.0 and later that causes clients to fetch
microdescriptors from fallbacks. So fallbacks (and authorities)
will have extra load until that's fixed.
