Bug reference:      18168

PostgreSQL version: 11.17
Operating system:   Windows Server 2019
Description:

This error happened in PostgreSQL 11.17, slightly more than 12 hours after
startup. I believe it's the first time this happens.

New firmware were installed on the server, this happened after restarting
the server. Since then, the database runs on a secondary server without
issue. That server received the same updates. We haven't tried moving it
back as this is our production database. Was this a fluke?

Looking online, the error code seems to refer to Windows sockets, with most
pages from the Windows XP era.

Startup: Oct 17 @ 11:40:20 PM
Shutdown: Oct 18 @ 11:43:15 PM

83 identical errors were logged in the system Event Viewer:
could not create inherited socket: error code 10106

Normal log until then. The application was running normally.
