Randall Meyer updated TS-3676:
------------------------------
Attachment: stacktrace.txt
A trimmed stack trace from one of the child hosts.
The missing lines are just repeating of these 4 calls:

> I have a parent/child cluster running without issue. Recently, I added a new
> map to a unresolvable name on the child host (in my example "resource_host").
> I set proxy.config.http.no_dns_just_forward_to_parent to 1 on the child.
> This worked fine for some time(many hours), serving up . But after awhile,
> the parent ATS-process crashes.
> 3 days later (with crashes happening every evening), I changed the config
> back to 0 and started using a name resolvable on the child. Since that
> change, there's been no crashes.
> This was observed on a set of 30 child hosts all dying with the same
> callstack.
