Hi all,
some weeks ago, my relay JPsi2 (F6EC46933CE8D4FAD5CCDAA8B1C5A377685FC521) started experiencing moderate stability problems. It would freeze after a few hours or days. The provider said it was due to Spectre mitigations and the only way for me to fix this would be to switch to a newer (more expensive) plan...
Some time later I did so and reinstalled it with Ubuntu 18.04 and placed the old keys into the new installation. It seems they are now expected to be in /var/lib/tor/.tor/keys, as opposed to /var/lib/tor/keys as I was used to in Ubuntu 16.04.
However, it does not seem to be making it into the consensus anymore. Only the authority nodes moria1, dizum, and longclaw vote for Running. The others don't.
So far I haven't been able to figure out the reason for that, so any help is appreciated.
Here is part of the output of journalctl -u tor and the torrc file:

What?
Your provider lied to you / scammed you, Spectre/Meltdown etc. mitigations have nothing to do with applications freezing or having to get a faster downstream/upstream speed.. at worst there's a 5-10% performance hit if you don't have the newest CPU microcode installed and an OS that makes use of the new insturctions (use the latest linux kernel and intel-ucode if you can).

It is possible that the provider wasn't fully honest in their statements. I have never experienced any instabilities due to CPU bug mitigations in any other machine, bare metal or VM.
But that isn't the issue.
The situation of my relay hasn't changed. It still isn't in the consensus. If it is caused by something on my side, I'd like to fix it sooner rather than later.

I copy the keys & the _fingerprint_ when I switch a relay to another server. Maybe this helps.
