Could you provide your Unit config and a clean unit log from when you start unit?

I'm curious what's generating these mesaages

The *40 and *41 entries look suspiciously like the connection ID value in a github.com/nginx/nginx error log.

Makes me wonder if this is the stderr dump from a Docker container with both nginx and unit installed and running???

There was an application running acme-dns that listened to port 443. The bug is that unit should not crash but exit with an error in this case.

Correct, Unit shouldn't crash, but I was unable to reproduce this.

If you can get a backtrace from a core dump that may help... or at the very least a clean log from starting Unit and it crashing, with nothing else going on like those other messages that appeared.
