Makes sense. The relay can't keep up with the extra load. It's basically a DDoS. It's gone into this state 4 times over the past ~ 48 hours.

I doubt this bug is the cause if it's just happened recently.
It's more likely that your relay is the HSDir for some popular
onion service. Or a genuine DDoS.

Can't your provider support that many connections?

Thanks the info. Unfortunately I upgraded to 0.3.1.7 before reading this (it didn't help), and can't figure out how to obtain 0.2.9.12 from the repos. I've tried these repos:


All of them seem to only offer 0.3.1.7, but I'm not sure I'm looking in the right places or querying apt in the right way.

A static link to a signed dpkg (for 0.2.9.12) would be fine for the moment, if anyone knows of one.

There's 0.2.9 nightly, but I don't know if we have an 0.2.9-release build.
