Intermittent network 1.4.2

Any current issues known with the networking turning off and on for RancherOS 1.4.2?

Just wrangled my cluster over to 1.4.2/1.6.24 and was heartbroken with the glitchy network.

Looking at a single node in a single environment to run my registry(nexus) and there’s no doubt the networking is just turning on and off. The registry exposes ports and is fronted by the F5 (HAProxy being too slow). This effect is masked in multi-node environments, the load balancers mitigate it, even though they also turn on and off.

Thanks for any info, I will open support ticket just wanted to see if I could narrow it down first.
