In our case, we are running 3 clusters on istio 1.3.3. On two of them (which are very similar - flannel, kube-dns and kubernetes 1.11.4) we are encountering this issue and on the 3rd one (cilium, coredns, kubernetes 1.12.7) there are no pods with high cpu envoys. All of them run workloads that range from low to high ops and have similar application patterns.
