Idle connections timeout

[xolott]

I'm having issues with our cluster using linkerd2. The app connects to Redis to subscribe and publish events. But after 10 minutes, the connection is closed, forcing a reconnect.

Running the app locally using the same Redis cluster works as expected, but its' closed every 10m in the k8s cluster. I checked the outbound Load Balancer resource in Azure and it's set up to timeout after 30 minutes.

Is there a setting in linkerd to control this behaviour? I think that in old versions we had idleTtlSecs but I can't find it in the docs for the latest version.

Linkerd doesn't enforce an idle timeout on opaque connections--if the application holds the connection open, linkerd should as well.

I'd recommend inspecting the proxy logs on both the client and server, which may include messages indicating a connection error. If there are not, you might try running with config.linkerd.io/proxy-log-level: linkerd=debug,info
