Flannel / iptables: resource temporarily unavailable #88148
Networking between (some) pods stops working, I could ping some containers from one of the host(s), but not others. Restart flanneld on the subset of nodes not responding might help. As we looked closer to this issue we started noticing iptables errors affecting flanneld, kube-proxy and kubelet.
Sometimes the issue my correct on its own or after a few hours, but worst case scenario nodes can suddenly die and stop responding, causing all kind of issues to the cluster, some side effects are connections dropped or latency.
