Rate limit error in default installation without additional settings istio 1.15

Colleagues, good afternoon, I often catch these errors in istio-sidecar, I did not add any additional settings to istio for the rate limit. istio 1.15

warn xdsproxy upstream [63] terminated with unexpected error rpc error: code = ResourceExhausted desc = request rate limit exceeded: rate: Wait(n=1) would exceed context deadline

warning envoy config StreamAggregatedResources gRPC config stream closed: 8, request rate limit exceeded: rate: Wait(n=1) would exceed context deadline (previously 14, error reading from server: EOF since 0s ago)

Please create an issue in Istio
