For months now (maybe years, who knows 🤷) I've had the following error sprinkled throughout my Kubelet logs across multiple of my worker nodes: StopPodSandbox from runtime service failed: rpc error: code = Unknown desc = failed to destroy network for sandbox "055b221e44a28ce8d9120f771d5e1ef201f2457ce49c58999a0147104cca2708": failed to get network "cbr0" cached result: decoding version from network config: unexpected end of JSON input As there has never been any associated impact with this that I could see I just ignored it... for a long time! Well, fast forward to last Friday night where a sudden hyper-focus hit and I decided I wanted to know what was going on and how to stop it - here's how it went.
