Nikola wouldn’t rebuild anymore but will continue serving the same content until you restart auto. Not producing any messages about file events anymore. Will continue serving the browser and will display load messages as usual.

On a side note, I was getting that broken pipe issue in the past. It was around that time when I implemented nikola serve -d and nikola auto --no-server. Auto is really a weird thing.

I see this was closed two years ago, but I'm getting this error a lot when using nikola auto. However, it seems to only happen with Firefox. It annoyed me enough I decided to try it with Chrome and suddenly this problem is gone.

Chrome is not my default browser though, so I have to switch between more windows now.

Anyway, not sure if I should reopen/create a new issue/...

Oops, just saw this wasn't actually an issue but a PR. (But, the log output included here is more similar to mine than the log messages in the linked issue.)

nikola auto was overhauled recently as part of v8 work. Could you test the master branch from GitHub and check if you get any errors like that?
