Intermittent DNS Cache Issue with nscd on glibc 2.28 After /etc/resolv.conf Updates

[debianyu]

Hi Florian,
Thank you for the clarification.
To confirm, is the specific bug you mentioned that was fixed in CentOS 8 Stream the same one tracked at this Red Hat Bugzilla link:
https://bugzilla.redhat.com/show_bug.cgi?id=1810142
Or does it refer to a different issue?

Thanks for your help.

Best regards,
Roy Yu
