Description

When configuring a shared zone to sync in an HA pair (for rate limiting) if the zone does not exist on the server it crashes the worker processes.

Snippet from config file:
#rate limiting State information for about 16,000 IP addresses takes 1 megabyte, so this zone can store about 160,000 addresses.
limit_req_zone $rateLimit zone=api_core:10m rate=15r/s sync;
limit_req_log_level error;
limit_req_status 429;

stream {

# TODO: NEEDS REGIONAL DNS
resolver 10.180.128.4 valid=20s;

server {

listen 40000;
zone_sync;
# TODO: FIGURE THIS OUT
zone_sync_server nginxvmss.attune.gshapps.net:40000 resolve;

}

}
