StreamAggregatedResources warning logs on 2.41+

[lsiqueira]

Hello,

After upgrading esp to 2.41 the following warning logs started:

[24][config]StreamAggregatedResources gRPC config stream to @espv2-ads-cluster closed since 317673s ago: 14, upstream connect error or disconnect/reset before headers. reset reason: connection termination

I'm using it in GKE with http only, with the following args:

        args:
            [
              "--listener_port=8081",
              "--backend=my-service:8080",
              "--service=my-service",
              "--rollout_strategy=managed",
              "-z",
              "healthz"
            ]

What can I do to fix this?

Just to mention that we too have been getting this warning and it's across several ESPv2 versions.

We get the same warning in the log even with a fixed rollout strategy. ESPv2 logs the warning about every 130 seconds.

As I understand it, it shouldn't be necessary to watch a fixed service configuration?
