This is causing failures in the pipeline, although for some reason it is not showing up in the PR: https://gitlab.com/f5/nginx/kic/kubernetes-ingress/-/jobs/1623726013

thanks for pointing out. forgot to update the template for N+ for Ingress, it still uses 256k default:
zone {{$upstream.Name}} {{if ne $upstream.UpstreamZoneSize "0"}}{{$upstream.UpstreamZoneSize}}{{else}}256k{{end}};
NGINX Plus R25 allocates more memory for storing upstream server (peer) data: +720 bytes per peer. This means upstream server zones will use more memory to accommodate that data. If a zone is full, NGINX Plus will fail to reload and fail to add more upstream servers via the API. To prevent reload failures after an upgrade to R25, this commit increases the default upstream zone size for NGINX Plus from 256K to 512K.
