TX Packets dropped on flannel.1 #1009
we are running a 14 node k8s cluster with flannel (backend: vxlan) and we are seeing some packet drops on the flannel.1 interface:
Under normal load (cpu about 20%) we are seeing 0.01pps getting dropped. If we are running some high traffic tests with iperf the dropping rate increases up to 1pps.
We are seeing this behaviour also on smaller clusters with only 3 oder 5 nodes.
