Issue #20172 has been updated by mwaldvogel (Michael Waldvogel).
We can at least exclude that it is due to heavy load. I will provide you access to one of
the vms by tomorrow. That way it should be easier to analyze.

Bug #20172: Socket.addrinfo failing randomly
https://bugs.ruby-lang.org/issues/20172#change-106141
* Author: mwaldvogel (Michael Waldvogel)
* Status: Open
* Priority: Normal
* ruby -v: ruby 3.3.0 (2023-12-25 revision 5124f9ac75) [x86_64-linux]
* Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN
----------------------------------------
I've recently updated one of my linux systems (Gentoo) to glibc 2.38 (that was the
only change). After the update most of the time the below error happens. Among other
things this breaks rubygems for me. I've reinstalled ruby 3.2.2 with rvm and
didn't encounter the issue. The issue however remained even after reinstalling ruby
3.3.0 and even with ruby master. Since this goes back to getaddrinfo (which is working
without any issues outside of ruby) and there seems to be only one bigger change to stdlib
socket, I'm assuming the problem was introduced with
https://bugs.ruby-lang.org/issues/19965
