Uri Shachar commented on TS-4514:
---------------------------------
Fix for this is quite simple - remove the no_dns treatment in the parent
selection code and mark the parent as down on resolving failure so we try
another if possible.
This also resolves TS-4404 on the way....
> Transaction hangs when no_dns_just_forward is configured but parent proxy is
> unresolvable

> When ATS is configured with:
> {code}

> And a transaction comes in that has an unresolvable parent in parents.config
> ATS will keep retrying to resolve the same parent.
