@paul, I suspect the '25' is 25 ipv6 addresses. Thats based on our debugging and fix we put into place. We started seeing the bug when a 10th ipv6 address was added to archive.ubuntu.com (and security.ubuntu.com). The workaround we put in place was to remove a single ipv6 address, resulting in 9 addresses.
So yes, it does just push the issue off, but a fairly large way off. @Amos, Thank you for your assessment. and pointer to the fix. ** Changed in: squid3 (Ubuntu Trusty) Status: Confirmed => Triaged ** Changed in: squid3 (Ubuntu Wily) Status: Confirmed => Triaged -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1547640 Title: proxy tries ipv6 and gets 503 when no ipv6 routes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/squid3/+bug/1547640/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
