Sounds like something in your container was causing some kind of DNS query loop, completely overwhelming the DNS server, causing it to drop requests and log that message.
We've never had any such report by other LXD users so it seems very likely to be something to do with your setup/container rather than a general problem in LXD's dnsmasq configuration. ** Changed in: lxd (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/1612422 Title: QtCreator is flooding the system with DNS queries To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-sdk-ide/+bug/1612422/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
