We know this doesn't occur on kubicctl clusters with multi-masters, which suggests haproxy somehow works around the issue. Recent snapshots have had the following recent changes which I suspect could be related (listed in invasiveness according to my opinion): - busybox package reworking - kernel update from 5.6.11 to 5.6.12 - minor runc patch - kured There is also the possibility that the cause is something else, I'm at a loss to be honest and trying to debug this just by going on what few clues we have here - any more data points and examples from people would be greatly appreciated. Given the bug report shows the problem occurs with earlier kured versions and with services other than kured, I think it's safe to rule out that update. Given the busybox package fundamentally changed every image we use for kubernetes, that was my first suspicion, so today I've built all of the images based on the busybox-free Tumbleweed base image (which is much larger, but obviously more likely to have everything each k8s component requires) You can get these images from registry.opensuse.org/home/rbrownsuse/branches/devel/kubic/containers/container/kubic However, as anyone who wishes to help can see, a cluster created with "kubeadm init --image-repository registry.opensuse.org/home/rbrownsuse/branches/devel/kubic/containers/container/kubic" still demonstrates this bug with a vengeance. I've even tried using the heavyweight base containers with the weave image, to no difference. So I'm pretty convinced our images/busybox are not at fault. This now leads me to wonder if the kernel or runc updates are to blame, which I will look at tomorrow, unless someone beats me to it first. Sorry that this doesn't look like it will be a quick fix. Anyone got any other info that might help? -- You are receiving this mail because: You are on the CC list for the bug.
