My theory is, also as Christer mentioned in comment 16, that we try to connect immediately after wake up, but since cached host name has expired we do complete name resolving again. But the system is not up that soon (few milliseconds after the wake up) to return some result. We should then not cache the unknown-host state.
I'm not a linux developer (I don't see this behavior on a Windows machine, but also may be just related to record expiration times) and also I'm not directly a DNS code maintainer (however, I can do the fix my self). Adding Michal, since he may know better what type of error state we get from getaddrinfo w/o a net connection up on a linux system. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/584529 Title: Thunderbird complains there is no connection on resume from suspend, when there is a connection To manage notifications about this bug go to: https://bugs.launchpad.net/thunderbird/+bug/584529/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
