`hGetBufSome: illegal operation (handle is closed)` in journalctl #66

Open quinn-dougherty opened 2 years ago

quinn-dougherty commented 2 years ago

I'm running the agent as a service in my nixos config. I use the flake as a module to install 0.9.7.

Here is some of my journalctl -u hercules-ci-agent.service

Critically, the only tasks being completed are evaluations. builds are stalled out completely. I don't think it's a cachix issue, as my caches are working fine when I do github action usage of them.

Something happened a few weeks ago that made all herc ci basically stall, whereas before it was working perfectly. I thought it was on the cachix end, but no longer think that.
