We are having the same issue. We are adding a ton of HttpRoutes these days with Traefik as GatewayApi. The problem lately is like you say. Crazy amount of warnings in the linkerd\_policy\_controller(linkerd-destination logs) BUT even worse is that we have now started to get sync errors in ArgoCD because of timeouts in the linkerd\_policy\_controller We get this in the linkerd-destination logs: > linkerd-destination-64dc9f9fd6-vw29x policy 2026-02-17T11:24:03.634466Z WARN [httproutes.gateway.networking.k8s.io](http://httproutes.gateway.networking.k8s.io): linkerd\_policy\_controller\_k8s\_index::outbound::index: Failed to convert route error=URLRewrite filter is not supported > linkerd-destination-64dc9f9fd6-vw29x policy 2026-02-17T13:20:51.371504Z INFO server{port=9443}:conn{client.ip=10.241.77.46 client.port=55624}: kubert::server: Connection lost error=read header from client timeout And we get this as an error in our ArgoCD sync: > Internal error occurred: failed calling webhook “[linkerd-policy-validator.linkerd.io](http://linkerd-policy-validator.linkerd.io)”: failed to call webhook: Post “[https://linkerd-policy-validator.linkerd.svc:443/?timeout=10s](https://linkerd-policy-validator.linkerd.svc:443/?timeout=10s)”: EOF,error when patching “/dev/shm/826766096” Can someone from Buoyant please take a look at this and comment. I can live with the warnings. They are just annoying and should be removed. But the BAD thing here is that the linked-destination pods stops responding and fails our ArgoCD syncs ---

I even tried to scale out linkerd-destination to 5 pods.

@william We could really need some feedback from Buoyant on this. As we are migrating all our Ingress resources to HttpRoute the number will grow a lot. And we are already hitting this issue with Linkerd. And Linkerd should not be a factor at all when using HttpRoute for ingress ---
