Leif Hedstrom updated TS-4648:
------------------------------
Fix Version/s: 7.0.0
> repeated DNS timeouts with an unresponsive server
> -------------------------------------------------
>
> Key: TS-4648
> URL: https://issues.apache.org/jira/browse/TS-4648
> Project: Traffic Server
> Issue Type: Bug
> Components: DNS, HostDB
> Reporter: James Peach
> Fix For: 7.0.0
>
>
> I have a server configured with 2 nameservers in {{resolv.conf}, and only the
> first one is responsive. I'm getting DNS timeouts on every new request while
> it fails over from the broken one to the good one.
> It is also really hard to debug this because none of the debug logs
> explicitly tell you what is going on with each server.
> First, this behaviour seems pretty suboptimal. Second, we need better
> observability (even improved debugging) that would help an operator figure
> this out.
