Envoy memory increase with no traffic - suspected xDS cause #8146

1.12.x

Kubernetes Version

None

Describe the bug

Envoy memory increases with no traffic after deploying a set of VirtualServices, Upstreams, and RateLimitConfigs.

If the gloo pod remains up after deploying the config and the initial xDS update then the Envoy memory increases ~30-50% higher than after the initial xDS update over time.

If the gloo pod is scaled down after deploying the config and the initial xDS update so that the config has been deployed then the Envoy pod memory reaches the expected state and is stable.

Steps to reproduce the bug

TBD

Expected Behavior

Envoy memory with no traffic and no config changes stays stable
