[jira] [Updated] (TS-4648) Repeated DNS timeouts with an
unresponsive server
[ https://issues.apache.org/jira/browse/TS-4648?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Bryan Call updated TS-4648:
---------------------------
Summary: Repeated DNS timeouts with an unresponsive server (was: repeated DNS timeouts with an unresponsive server)
> 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.
