Re: Downtime when traffic_ctl config reload
You could also enable parent.config debug logging that would help in troubleshooting this in records.config set: CONFIG proxy.config.diags.debug.enabled INT 1 CONFIG proxy.config.diags.debug.tags STRING parent_select # traffic_ctl config reload On 1/12/19, 10:15 AM, "Miles Libbey" wrote: A loop would indicate its not matching parent.config then.

In https://docs.trafficserver.apache.org/en/8.0.x/admin-guide/files/parent.config.en.html it has a dest_ip field that would seem to make more sense than dest_domain|host for that map rule.
