If you have a linkerd.yaml file with the following servers config: ``` servers: - port: 80 ip: 0.0.0.0 socketOptions: readTimeoutMs: 601000 writeTimeoutMs: 601000 keepAlive: true backlog: 128 ``` the defaults are not applied correctly as stated in the docs: https://api.linkerd.io/1.6.3/linkerd/index.html#socket-options Here is the section from /config.json for the above config: ``` "port": 80, "socketOptions": { "noDelay": false, "reuseAddr": false, "reusePort": false, "writeTimeoutMs": 601000, "readTimeoutMs": 601000, "keepAlive": true, "backlog": 128 }, ``` We have a test patch ready, and will be submitting that later this afternoon.
