Thanks for taking the time to file this bug and try to make Ubuntu better. I suppose you are talking about 'tcp-initial-timeout' config option which the upstream default is 30 seconds (300 * 100 milliseconds). Am I right? Or are mentioning something else?
FWIW I got this info from upstream doc: https://bind9.readthedocs.io/en/v9_16/reference.html I checked if in the source package available in Ubuntu any change to this config option was made and I found nothing. So I am not so sure if this is indeed a problem in the packaging side. Could you please provide your config files and how can I reproduce this? That'd help to determine whether this is a bug. For now I marking this bug as Incomplete but when you provide more details please set the Status back to New and we will revisit it. ** Changed in: bind9 (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1909950 Title: TCP connections never close To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bind9/+bug/1909950/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
