First, that’s a really old version of ATS, one that is EOLifed already. You
should consider upgrading to an LTS version.
That much said, there are a few options to examine:
proxy.config.http.no_origin_server_dns (0 by default)
proxy.config.dns.failover_number (5 by default)
proxy.config.dns.lookup_timeout (20 by default)
There are a few others that might be related. Also, i thought we had a Jira
about not successfully being able to use that first setting, but I can’t find
it. Try it, and see what happens.
