ConnectionResetError: Cannot write to closing transport

and I have noticed in my configurator I am getting tons of core.PID files.

any ideas?

I also have endless of these errors (now on 0.90).
Any new insights?

Nope, you’re the first to reply. I still have them and I’m on the latest version.

Haven’t figured out a way to get the core files analyzed either…
